Essays on Nervous System

Throughout pregnancy the nervous system is continuously growing and developing more than any other system in the body. The nervous system can be divided into the central nervous system (CNS) and peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, while...

A majority of the students get to class by walking through the campus; I am no exception. This might appear as a simple task, getting from point A to B, utilizing the basic movement of the two legs; but underneath, this process is much more...

Neurons are the basic and operative units of our nervous system. They have three parts: the soma or cell body, the dendrites, and the axon. The soma is the centre of the neuron. Its shape is variable and energy for the functioning of the neuron...

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder characterized by upper and lower motor degeneration. Riluzole is the only FDA approved drug for ALS. Although it has adverse effects such as nausea, reduced liver function, asthenia or pneumonia, in many cases Riluzole is revealed...

The normal function of the mammalian central nervous system (CNS) is largely dependent on structural plasticity. This plasticity can be modulated by a variety of environmental and endogenous factors. Changes in dendrite morphological may be associated with altered region-specific function and behaviour. The hippocampus is...

Over the past few decades, it has become increasingly evident that androgens are powerful modulators of hippocampal neuroplasticity. However, despite most studies demonstrating a trophic influence of androgens on spine synapses there is evidence to suggest these changes contrast with modifications to dendritic arborization. Two...

The CA1 region of the male rat hippocampus has been shown to exhibit a reduction in spine synapse density one-month following GDX (Leranth et al. , 2003). Although this result closely parallels the reduction in spine synapse density seen in females rats following ovariectomy (MacLusky...

It is estimated that in the United States, 60,000 individuals are diagnosed with Parkinson’s disease each year and that as many as 1 million Americans have Parkinson’s disease (VanMeter, K. C. & Hubert, R. J. , 2018). This specific disease has a defectiveness of the...
