Brief introductory description of physiology of the central nervous Essay

Brief introductory description of physiology of the central nervous system related to Parkinson's disease - Essay Example This is a degenerative disease of the central nervous system that ultimately targets the dopamine generating cells situated in the substantia nigra a region in the midbrain. Once the dopamine generating cells have been destroyed, the synchronization of movement by both the brain and the spinal cord is affected. (Weiner, Shulman, & Lang, 2013 pg.21). A precise study and diagnosis of the disease is characterized by the buildup of a protein called alpha-synuclein in the neurons specifically in the inclusions of the neurons called the Lewy bodies. Since this directly affects the neurons, the formation and activity of dopamine, which is formed by certain neurons in the some sections of the midbrain are also disrupted. The accumulation of this protein cause a massive death of dopamine producing neurons, and the inevitable outcome is the Parkinson’s disease. The seriousness of the disease will depend on the distribution of the Lewy bodies within the neurons, and the more the distribution, the higher the rate of manifestation of Parkinson’s disease. (Tseng, 2009 pg93). It has been determined that the Parkinson’s disease is rampant in old age than it is in younger people, it rarely affect young individuals unless some heredity factors come into play.

The question then becomes how school districts can have any sort of regularity to them if they are all teaching in different languages.
