French Revolution Essay Example for Free

French Revolution Essay To fully explain the root cause of Modern Nationalism, one must look into what has transpired in the French Revolution. In 1789, the French revolution was born. There were transitions of power acquisition in the vital parts of Europe. On the 14th of July 1789, Bastille was under siege and on October the King Louis XVI and Royal Family was dethroned from Versailles and ended up to Paris. King Louis XVI was the ruler back then so his downfall can be equated to a total loss of order and authority. There were several attempts to escape the ouster of King Louis XVI but unfortunately it failed. With no clear power over the vast land, an assembly was formed to have a well-rounded and organized republic comprised of Austria, Holland, Prussia and Sardinia. When the republic was formed, King Louis was executed for his tyranny which have entailed for the sprouting of the Revolutionary Tribunal. France did not participate with this ideology because of the resistance of Napoleon Bonaparte. Napoleon Bonaparte acquired control of the Consulate to proliferate a uniform law, equality, property rights and eradication of feudalism. Geographically, France is situated between the two large clusters of the liberal advocates. Basically, the French Revolution was the clash between the liberals and the radicals. Liberalists are those people who adhere to a just society through the divine law that is hereditary through culture while radicals are those who adhere to line of thinking that change and variation from the old system must manifest for a better society. From the clashes of the two opposing ideologies of the French Revolution, a new ideology was formed which is the Modern Nationalism. Nationalism is an ideology which focuses on the unity of the members of the nation to have a single national identity given basis to ethnicity, origin and the cultural background of these nations (Miscevic, 2005). The essence of adhering to the Nationalist Ideology is to establish a state. A state is political entity that is assumed to have a high degree of sovereignty (Miscevic, 2005). The state has a high sovereignty because it is assumed that the power is centralized with this entity. All of the members of the nation must abide to the imposed terms and conditions made by the state. The state can be polymorphous in way that it can be democratic and also can be totalitarian. The two opposing kingdoms of Italy and Germany were united. Despite of their contrasting beliefs, they found a way to remedy the situation and push through for the development of the nation. In 1871, they were united but the times went sour when the nation needed a sole leader of the two states. It is assumed and predicted that there will be conflict between Italy and Germany because of their adherence to Liberalism and Nationalism, respectively. Guissepe Mazzini was a radical revolutionary thinker that viewed the Italy as a state under an umbrella of control by a foreign authority. He wanted to free Italy from nationalistic ideology that it has adhered to since he was a liberalist. With his propaganda mission, he was put into bars in Italy. His revolutionary act were extremely refuted by the nationalist view hence he did not stop pursuing his effort of shifting Italy to a liberal state. Nationalism is a good ideology but it has some loopholes like any other ideologies. Some of them are: it is too predictive and presumptuous, why, because it always aims to unite people that are completely different from one another. Cultural relativism can be an issue for nationalism. Second, the selection of state that will be the center of authority, this is very important hence no one could tell what possible qualities should a good state possess and it all boils down to who has the greater means of production. Lastly, it assumes that the world possesses a harmonious relation, but in reality, we are driven by conflict. References Cody, D. (2007). French Revolution. The Victorian Website. Hartwick College.

Racism in the Film Remember the Titans Essay -- Movie Film Football Ra

In the movie "Remember the Titans" there are many lessons that every person should learn in their life. One of the most important lessons is that of racism. In this day and age some people believe that racism is over because there are no longer any slaves, some people believe that there is still racism but that it is ok. I believe that those people would benefit a great deal from seeing this movie. I know that there is still racism, I also know that it is not ok. There is a scene in this movie where the coach takes the team on a long run in the middle of the night. They end up at the break of dawn at a cemetery. The coach tells the young men of the battle that was fought on that ground. He told of the blood shed on those grounds that turned the whole area red. This can help many people that want to make a difference in this world. They had to stand up for their new knowledge to people that they love and trust. The people in this story go through a great transformation from hating each other to being as close as brothers but I do not feel that the end result is the most important part. These boys had very difficult decisions to make. I think that all these young men were raised to be racists to varying degrees. This graveyard moment was a very clear message that could not be misunderstood. They learned tolerance for those of their loved ones that couldn?t or wouldn?t learn as quickly as they did. If we are to ever overcome the misguided beliefs we gain from our parents we need a very good explanation of why we should believe another way. Without this I do not think that the team would have ever come together because they had been raised to hate each other their whole life. The learned the importance of friendship and what i... ...n effort to get along. Their friendship was so secure and they were so pleased that they had learnt to overcome the racial issues and spent the time to get to know each other. They both still acted as if they were better than each other and they weren?t going to attempt to change this, even when they were playing football together. If something went wrong they would blame each other, or disagree, and always end up fighting and usually about different things, like who was better and right. By observing the friendship emerging between Gerry and Julius other people began to realize that having friends of a different race was not wrong. This also made Gerry and Julius?s friendship grow even stronger as they made a huge impact on the community. They started to understand each other and created a bond that was so strong that their appearance didn?t seem to matter anymore.

Discuss the Role of Endogenous Pacemakers and Exogenous Zeitgebers.

There are 3 biological rhythms in the body. Circadian, which is our body clock which works to a 24-hour cycle and regulates our bodies biochemical, physiological and behavioural processes. Ultradian processes, which are smaller processes that happen inside our 24-hour circadian cycle. These Ultradian cycles are the sleep stages lasting 90-120 minutes, however some other ultradian cycles include hormone release, heart rate, nostril dilation and appetite. Lastly there is Infradian which are outside our circadian 24-hour cycle such as the menstrual cycle and hibernation. These cycles are endogenously controlled, however can be tainted or ‘entrained’ to the environment by exogenous factors. Endogenous pacemakers are biological pacemakers inside us that regulate our cycles. An endogenous pacemaker is the Suprachiasmatic nucleus located in the hypothalamus. It is situated directly above the optic chiasm (allowing it to respond to light) and it responsible for controlling circadian rhythms. At the presence of light, it stimulates the pineal gland to release melatonin. Melatonin is a naturally occurring hormone that promotes sleep. A higher level of melatonin will promote sleep, and thus a lower level will help us wake up and stay alert. It’s this process that endogenously regulates our circadian sleep-wake cycle. The SCN’s influence on our bodies has been demonstrated in Morgans animal study. He bred ‘mutant’ hamsters with entrained ’20-hour’ circadian rhythms. When their SCN was transplanted into their ‘normal’ hamsters they exhibited the mutant rhythm. This shows the role the SCN plays in our circadian cycles, showing it regulates our sleep patterns and that rhythm entraining is done through the SCN. However, this argument can be deeply flawed. The SCN affects other circadian rhythms such as hormone release and these could affect sleep itself as well as individual differences; therefore it may be deterministic to conclude that the SCN is the regulator of sleep. Methodological issues are thrown into the research also. Is the research ethical justifiable? In my opinion, in groundbreaking findings drawing the link between the SCN and sleep it is justifiable to use rats however rats are not similar to humans and therefore cannot be well generalised.

Magical Realism in Context Analysis of A Very Old Man...

Magical Realism in Context: Analysis of A Very Old Man with Enormous Wings From the beginning of A Very Old Man with Enormous Wings, the ordinary begins to confront the extraordinary. This short story by Gabriel Garcia Marquez, one of the most famous Latin American authors, was introduced to the world in 1955. By examining the magical and realistic elements of this short story, the theoretical term given to an emerging art form of the mid- twentieth century can be applied to a work of literature. Marquez does not waste time ushering in the magical elements of A Very Old Man with Enormous Wings. The main character of the story, Pelayo, was coming back to his house after throwing away many crabs that had come into†¦show more content†¦All she needed was one look to show him his mistake-the old man was an angel, she thought (Marquez 525). Many other unreal or magical events occur throughout Marquezs short story. One amusing instance occurred when the citizens were making conjectures about the old mans future. One suggested that he should be named mayor of the world-clearly an extraordinary idea! Others thought he could implant on Earth a race of winged wise men to take charge of the universe (Marquez 526). Another hilarious instance occurred when a citizen tried to make the old man eat mothballs. Mothballs, according to the wisdom of a wise neighborhood woman, were the food prescribed for angels (Marquez 527). Although many magical elements exist throughout A Very Old Man with Enormous Wings, these unreal occurrences are balanced with realistic elements. Even though the old man had wings, he was otherwise quite normal. The parish priest commented that he was much too human, much too dirty and weathered to be measured up to the proud dignity of the angels (Marquez 527). The surrounding characters act in a normal manner. Pelayos wife, Elisenda, seeks to capitalize on the angel in their chicken coop, charging five cents admission to see him (Marquez 526). With this money they later built a mansion (Marquez 528). Unlike many fantastic works where money or value of property is considered to be much too worldly and greedy, this short story contains elements of theShow MoreRelatedMagical Realism As A Sense Of Psychological Mystery And Wonder3415 Words   |  14 PagesMagical realism, at its very root, has always involved a sense of psychological mystery and wonder; partly due to its intended audience, which may range from mere children to adults seeking a sense of spirituality or morality through verbatim.

A Review of Facial Nerve Anatomy Essay Sample free essay sample

An intimate cognition of facial nervus anatomy is critical to avoid its accidental hurt during face lift. parotidectomy. maxillofacial break decrease. and about any surgery of the caput and cervix. Injury to the frontlet and fringy inframaxillary subdivisions of the facial nervus in peculiar can take to obvious clinical de?cits. and countries where these nervousnesss are peculiarly susceptible to hurt hold been designated danger zones by old writers. Appraisal of facial nervus map is non limited to its extratemporal anatomy. nevertheless. as many clinical de?cits originate within its intratemporal and intracranial constituents. Similarly. the facial nervus can non be considered an entirely motor nervus given its parts to savor. otic esthesis. sympathetic input to the in-between meningeal arteria. and parasympathetic excitation to the lacrimal. submandibular. and sublingual secretory organs. The configuration of de?cits ensuing from facial nervus hurt is correlated with its complex anatomy to assist set up the degree of hurt. predict recovery. and steer surgical direction. KEYWORDS: Extratemporal. intratemporal. facial nervus. frontal nervus. fringy inframaxillary nervus he anatomy of the facial nervus is among the most complex of the cranial nervousnesss. In his initial description of the cranial nervousnesss. Galen described the facial nervus as portion of a distinguishable facial-vestibulocochlear nervus composite. 1. 2 Although the anatomy of the other cranial nervousnesss was accurately described shortly after Galen’s initial descriptions. it was non until the early 1800s that Charles Bell distinguished the motor and centripetal constituents of the facial nervus. Facial nervus anatomy is categorized in footings of its relationship to the braincase or temporal bone ( intracranial. intratemporal. and extratemporal ) or its four distinguishable constituents ( branchial motor. splanchnic motor. general sensory. and particular sensory ) . The plastic sawbones bene?ts from a basic cognition of the intracranial and intratemporal constituents of the facial nervus to assist place facial nervus pathology and distinguish extratemporal from facial nervus lesions at other anatomic locations. Similarly. a cognition of the four distinguishable constituents of the facial nervus reminds the sawbones that the facial nervus is composed non entirely of voluntary motor ?bers but besides of parasympathetics to the lacrimal. submandibular. and sublingual secretory organs ; centripetal excitation to portion of the external ear ; and parts to savor at the anterior two tierces of the lingua. INTRACRANIAL ANATOMY OF THE FACIAL NERVE Voluntary control of the branchial subdivision of the facial nervus is initiated intracranially by supranuclear inputs originating from the intellectual cerebral mantle projecting to the facial karyon. These cortical inputs are arranged with forehead representation most rostral and palpebras. midface. and lips consecutive caudal to this. 5 The pyramidal system is composed of corticobulbar piece of lands that project voluntary. ipsilateral cortical inputs via the knee of the internal capsule to the 7th cranial nervus karyon of the pontine tegmentum. Cell organic structures of the upper facial motor nervousnesss giving rise to the frontal subdivision receive bilateral cortical inputs. and nerve cells to the balance of the facial karyon receive contralateral cortical excitation. Spontaneous facial motions are centrally transmitted via the extrapyramidal system. which involves diffuse axonal connexions between multiple parts including the basal ga nglia. amygdaloid nucleus. hypothalamus. and motor cerebral mantle. The extrapyramidal system regulates resting facial tone and stabilizes the voluntary motor response ; hypothalamic inputs modulate the emotional response. The facial karyon contain the cell organic structures of facial nervus lower motor nerve cells. These cell organic structures receive supranuclear inputs via synapse formation with axons going through both the pyramidal and extrapyramidal systems. The con?uence of these postsynaptic lower motor nerve cells round the abducents nucleus and organize the facial colliculus at the ?oor of the 4th ventricle ( Fig. 1 ) . The branchial motor subdivision of the facial nervus exits the brain-stem at the cerebellopontine angle. where it is joined by the less robust nerve intermedius. These nervousnesss resemble the nervus roots of the spinal cord in that they are barren of epineurium but covered in pia mater and bathed in cerebrospinal ?uid. The branchial motor nerve–nervus intermedius complex travels about 15. 8 millimeter from the cerebellopontine angle before it begins its class within the temporal bone. 6 The parasympathetic constituent of the facial nervus is composed of splanchnic m otor ?bers whose arising cell organic structures are scattered within the pontine tegmentum and jointly known as the superior salivatory karyon. These karyons are in?uenced by nonvoluntary hypothalamic inputs. Cell bodies interceding the general centripetal map of the facial nervus reside in the general centripetal trigeminal karyon of the rostral myelin and receive sensory nerve inputs from projections of the geniculate ganglion within the temporal bone. The gustatory karyon within the pontine tegmentum besides receives particular centripetal inputs from the geniculate ganglion. These urges. nevertheless. were ab initio generated by gustatory sensation receptors in the anterior two tierces of the lingua. Ascending centripetal inputs from the trigeminal and gustative karyons are in?uenced by the thalamic karyon prior to their response within the centripetal cerebral mantle. Patients with supranuclear lesions affecting the motor cerebral mantle or internal capsule present clinically with loss of volitional control of the lower facial muscular structure but relentless facial tone and self-generated facial motions. Voluntary control of the forehead muscular structure is retained because the upper halves of the facial karyon. which are populated by frontal nervus subdivision cell organic structures. receive bilateral cortical excitation and so non all input is lost after a one-sided supranuclear lesion. Voluntary lip. nose. and cheek motions. nevertheless. are lost. It should besides be noted that facial musculus disfunction caused by cardinal hurt is often accompanied by motor disfunction of the lingua and manus given the propinquity of these cortical control centres within the motor cerebral mantle and internal capsule. Re?ex arcs affecting the facial karyon. such as the corneal wink ( trigeminalfacial ) . are preserved following supranuclear lesions. INTRATEMPORAL FACIAL NERVE The intratemporal anatomy of the facial nervus has been extensively studied to minimise morbidity in skull base surgery while maximising exposure. In add-on. its intraneural topography has been investigated in corpses and carnal theoretical accounts. 7–9 Whereas the topography in certain carnal theoretical accounts. such as the cat. is shown to be consistent. the topography of the intratemporal facial nervus in the human is extremely variable and spacial relationships to other intratemporal constructions such as the carotid arteria and sigmoid fistula are besides variable. 10–13 The ramification form of the intratemporal facial nervus. nevertheless. is moderately consistent. The branchial motor and nervus intermedius constituents of the facial nervus are slackly associated as they enter the internal auditory meatus of the temporal bone. Both the seventh cranial nerve and acoustic nervousnesss enter the temporal bone at the same time with the facial nervus located superi or to the acoustic nervus. The facial nervus. along with the acoustic and vestibular nervousnesss. travel 8 to 10 millimeters within the internal audile canal before merely the facial nervus enters the fallopian canal. The fallopian canal consists of labyrinthine. tympanic. and mastoid sections. The labyrinthine section is the narrowest section and extends 3 to 5 millimeter from the border of the internal audile canal. The geniculate ganglion resides within the distal portion of the labyrinthine section of the facial nervus and gives rise to the ?rst subdivision of the facial nerve—the greater petrosal nerve—which carries splanchnic motor parasympathetic ?bers to the lachrymal secretory organ ( Fig. 2 ) . The external petrosal nervus is a 2nd. threadlike subdivision that is on occasion present and provides sympathetic excitation to the in-between meningeal arteria. The lesser petrosal nervus is the 3rd subdivision widening from the geniculate ganglion. This subdivision typically carries parasympathetic ?bers associated with the glossopharyngeal nervus ( 9th cranial nervus ) to the parotid secretory organ. Salivary ?ow from the parotid secretory organ may non. nevertheless. be interrupted by lesions to the glossopharyngeal nervus. In fact. parasympathetic ?bers going along the nervus intermedius of the facial nervus can short-circuit the glossopharyngeal subdivision to the parotid and supply an alternate beginning of parasympathetic excitation to keep salivary ?ow. Compaction of the facial nervus within the labyrinthine section is peculiarly common given the canal’s narrow dimensions. The facial nervus occupies up to 83 % of the labyrinthine canal cross-sectional country compared with merely 64 % of the more distal mastoid country. 14 The junction of the labyrinthine and tympanic constituents of the fallopian canal is formed by an acute angle. and shearing of the facial nervus normally occurs as the nervus traverses this knee. 8 The tympanic or horizontal section extends 8 to 11 millimeters through the temporal bone. The midtympanic canal represents a 2nd part of fallopian canal narrowing and is a less common point of nervus compaction compared with the narrow labyrinthine section. 15 The tympanic secti on connects with the mastoid section at a 2nd knee. The voluntary motor constituent of the facial nervus exits the cerebellopontine angle with the nervus intermedius before come ining the porous acusticus. The facial nervus traverses the labyrinthine section before come ining the geniculate ganglion. The greater petrosal. external petrosal. and lesser petrosal nervousnesss are given off at this degree. The temporal or horizontal section forms the 2nd constituent of the intratemporal facial nervus and is located merely distal to a crisp knee formed at the distal geniculate ganglion. A 2nd knee separates the temporal and mastoid sections of the intratemporal facial nervus. The general centripetal subdivision of the facial nervus is given off at this degree and often travels with the general centripetal subdivision of the pneumogastric nervus ( Arnold’s nervus ) and gives esthesis to the external ear. The nervus to stapedius is a motor nervus that helps dampen loud sounds. The chorda kettle is the last subdivision of the intratemp oral facial nervus and is the terminal subdivision of the nervus intermedius. Wider cross-sectional country than the other sections. and the facial nervus gives off three subdivisions within this part. The nervus to the stapedius is the ?rst subdivision and innervates the stirrups musculus of the interior ear. Because the cell organic structures of this motor nervus are non located in the facial karyon. patients with inborn ? facial paralysiss such as Mobius syndrome retain excitation to the stirrups when the other facial mimetics are paralyzed. 8 The centripetal subdivision of the facial nervus is typically the 2nd subdivision. Ramsay Hunt ?rst noted this general sensory nervus in 1907 when patients showing with facial palsy related to herpes shingles besides demonstrated a vesicular eruption limited to parts of the external ear. 16 Ten cadaverous temporal bone dissections revealed a little subdivision off the perpendicular constituent of the intratemporal facial nervus that arced laterally and inferiorly to provide the buttocks and inferior external auditory canal. Tumor encroachment upon this centripetal nervus. which is thought to consist 10 to 15 % of the nerve cells within the intratemporal facial nervus. 17 consequences in hypoesthesia of the external ear canal and is known as Hitselberger’s mark. after the doctor who described it. The general centripetal subdivision of the facial nervus travels with Arnold’s nervus. a centripetal subdivision of the pneumogastric nervus that exits the jugular hiatuss and so joins the class of the facial nervus merely distal to the nervus to the stapedius subdivision. 8 The chorda kettle is the terminal extension of the nervus intermedius. It branches off the facial nervus in the distal tierce of the mastoid section and runs between the bonelets of the in-between ear before go outing the tympanic pit through the temporal bone at the petrotympanic ?ssure. It joins the linguistic subdivision of the trigeminal nervus to supply parasympathetic excitation to the submandibular and sublingual secretory organs. Particular centripetal sensory nerves from the anterior two tierces of the lingua besides travel with the chorda kettle. and on juncture the centripetal subdivision of the facial nervus travels with the chorda kettle alternatively of posteriorly to the chief facial nervus bole. Advocates of this technique note that harm to a little subdivision of the facial nervus during the initial geographic expedition is far less lay waste toing than an accidental hurt to the full motor bole. However. these peripheral subdivisions are more dif?cult to place because of their smaller size and a deficiency of consistent landmarks. The arborization of the extratemporal facial nervus typically begins within the substance of the parotid secretory organ and finally gives rise to the cervical. fringy mandibular. buccal. zygomatic. and frontal ( or temporal ) nervus subdivisions. Davis et al dissected 350 cadaverous facial halves and were the ?rst to categorise the ramification form of the facial nervus into six distinguishable forms. 20 The facial nervus bole typically gave rise to superior and inferior divisions. The fringy mandibular and cervical subdivisions of the facial nervus were entirely derived from the inferior division. whereas the buccal subdivision ever received some part from the inferior division and either no or a variable part from the superior division ( Fig. 3 ) . The frontal subdivision systematically represented a terminal subdivision of the superior division of the facial nervus bole. Baker and Conley reviewed the extratemporal facial nervus anatomy in 2000 parotidectomy instances. 21 Their ?n dings suggested that the facial nervus ramifying form was more variable than that noted in Davis’ cadaverous surveies. including the presence of a facial nervus bole trifurcation with a direct buccal subdivision in a few cases. EXTRATEMPORAL FACIAL NERVE The extratemporal constituent of the facial nervus starts when the facial nervus exits the stylomastoid hiatuss. In the grownup. it is protected laterally by the mastoid tip. tympanic ring. and inframaxillary ramus. whereas in kids younger than 2 old ages it is comparatively super?cial. Postauricular scratchs in this younger population must be carefully planned because the bole of the facial nervus is a hypodermic construction at this degree. After go outing the stylomastoid hiatuss. the facial nervus gives off motor subdivisions to the posterior abdomen of digastric. stylohyoid. and the superior auricular. posterior otic. and occipitalis musculuss. The facial nervus so travels along a class front tooth to the posterior abdomen of the digastric and sidelong to the external carotid arteria and styloid procedure before spliting into its chief motor subdivisions at the posterior border of the parotid secretory organ. The facial nervus bole is normally identi?ed about 1 cm deep and merel y inferior and median to the tragal arrow. The parotid and super?cial musculoaponeurotic system ( SMAS ) can so be carefully divided to expose the facial nervus for facial nervus Reconstruction. Mentions 1. O’Rahilly R.
