that allow us to visualize the condition of the substantia nigra. A key pathological feature of Parkinson’s is based off the microscopic anatomy of the substantia nigra showing Lewy bodies‚ which are irregular collections of protein that form inside neurons‚ appearing as spherical masses that take up the space of cellular components (Iacono‚ et al.‚ 2015). You can think of it as a blood clot that doesn’t allow the passage of blood through a vessel. Besides that‚ neuronal loss is accompanied by the death

network of neurons (nerve cells) that that sends information to the brain to be analyzed. Neurons live both in and outside the central nervous system. Understanding how the neurons work is vital to understanding the nervous system. Neurons The neuron has two important structures called the dendrite and axon‚ also called nerve fibers. The dendrites are like tentacles that sprout from the cell and the axon is one long extension of the cell. The dendrites receive signals from other neurons‚ while the

including neurons and glial cells. Neurons are cells that send and receive electro-chemical signals to and from the brain and nervous system. There are about 100 billion neurons in the brain. There are many more glial cells; they provide support functions for the neurons‚ and are far more numerous than neurons. There are many type of neurons. They vary in size from 4 microns (.004 mm) to 100 microns (.1 mm) in diameter. Their length varies from a fraction of an inch to several feet. Neurons are nerve

sporadic (SALS) forms. Because SOD1 is found in the intermembrane space of the mitochondria and mitochondrial swelling and vacuolization are signs of motor neuron death‚ it was theorized by Okado-Masumoto that the uptake of this mutated SOD1 caused the motor neuron death (Okado-Matsumoto 2002). ALS progresses inexorably‚ eventually effecting bulbar neurons and cranial never motor nuclei. Because of this patients that are near the final stages of this disease often need substantial medical care to live.

Writing Assignment #2 #1- Sleep deprivation is a common problem in modern society. Sleep plays a crucial role in optimal health and wellness throughout a person’s life. Getting a proper amount of sleep can help aid in mental and physical health. Sleep deprivation can occur from various causes. Often the stresses and vigor of daily life may intrude upon our ability to sleep well. In any case‚ sleep deprivation is not only detrimental to one’s well being‚ but it can also impair cognitive ability and
