The Human Body: The Nervous System

The human Body is a very complex organism. It is composed of many different organs systems, which are vital for the body to function properly. They work with one another in order to carry out daily life activities and maintain the body’s proper functions. Among these organ systems lies one of the most important, the nervous system. The nervous system functions as the control center of the body, and it is in charge of the activities of the rest of the organs systems and the body’s components (Marieb, E.N. & Hoehn, K.). It helps the body communicate external environmental factors via electrical impulses that are transmitted through cells called neurons. These neurons can be up to a meter long and target a specific effector which it will help
The first one is the central nervous system which includes the brain and the spinal cord. The nerves of these two structures are in control of body movement. The second division includes the rest of the nerves and ganglia that are not included in the central nervous system, which serve as communications relay and it’s known as the peripheral nervous system (Marieb, E.N. & Hoehn, K.). The existence of both divisions is very important because their function is necessary in order to maintain a homeostasis. The peripheral nervous pick up stimuli through receptors from the external environment. Stimuli is then sent to the brain for processing via afferent sensory neurons. Once the brain receives the information and processes it, it send a response via efferent sensory neurons. The response gets to effector muscles which can now react to the situation on the external environment. If one or more nerves in either one of the two divisions is damaged, the person’s body would not respond properly to the brain’s demands, putting the person’s life in danger. For this reason, illnesses that put the nervous system at risk of getting damaged need to be taken care of as soon as they are
Most of these drugs have been proven to be efficient when tested in animal subjects. The drugs are capable of slowing down the progression of the disorder and making the symptoms less prevalent. The two most effective drugs used are miconazole and clobetasol. These had the ability of “promoting precocious myelination in organotypic cerebellar slice cultures, and in vivo in early postnatal mouse pups” (Najm, F.J. et al). In addition, these drugs have a major effect in two different components of the disease. Miconazole allows the increment of oligodendrocytes and makes remyelination more likely to occur while clobetasol targets the immune system directly as a strong immunosuppressant. Differently from medical drugs, other methods used to alleviate symptoms are therapy treatments. Physical therapy is commonly used, as it helps stimulate muscle tissue allowing it to maintain mobility. Although long terms effects are rarely reported, there are many reports stating that exercises helps decrease the amount of limitations that multiple sclerosis present in the patients (Doring , A. et.
