Central nervous system

Multiple sclerosis (MS) is a muscular disease that affects the central nervous system (CNS) which consists of the brain and the spinal cord. This disease was discovered by Dr. Jean Martin Charcot. Eventually, improvements in microscopes helped doctors in the search of understanding the disease. In 1916, a Scottish doctor named James Dawson was able to clearly describe the inflammation after viewing the brain cells of a patient with multiple sclerosis through a microscope. Over the years,…

(2015) nervous system divided into two division which is the Central Nervous System(CNS) and Peripheral Nervous System(PNS). CNS consist of the brain and spinal cord while PNS include all the neural tissue outside the CNS. Neuron are the nerve cells which receive the stimulus from each part of the body and send it to the CNS. A neuron consist of body cell, dendrites, axon,myelin sheath and telodendrites. Normal neuron requires all the structure works together forming a good nervous system. The…

In the world today, there are about 5000 languages spoken. Where the languages originated from is the unknown factor that the humans have been studying for the past two centuries. Experts have linked the similarity of languages by the shared words, sounds, or grammatical constructions. There are specific names classified for people who speak a certain number of languages. People who speak one language are termed monolinguals. People who speak two languages fluently are termed bilinguals. People…

Imagine a world without music. There would be no such thing as rhythm, tempo, harmony, pitch, and many other elements that make up one of the most cherished ideas on Earth. Proms and homecoming dances would not be the jumpy, yet romantic, nights that couples dream of. The people would be missing an irreplaceable piece of the heart. While music is an important part of the heart and the soul, some have the audacity to say that music is a distraction. While it may be getting in the way of doing…

Did you ever aspire to be a scientist with a specialty in the study of the brain? If you did not know, a neurologist is a scientist that studies and treats disorders of the nervous system, which includes the brain and spinal cord (De Petro, MaryAnn). There are a lot of neurologists out there already, but the demand for doctors in that field is growing. As Wilder Penfield once said, “The brain is the organ of destiny. It holds within its humming mechanism secrets that will determine the…

discussed simplified algebraic model. The amalgamation of various models related to CSF flow will enable the elimination of certain limitations presented in each work. For example, the model presented by Elliott [1] incorporates the multisegmented system and provides a fairly useful, yet unrealistic,…

Spina bifida is a genetic birth defect that affects the development of the spinal cord. In babies who contract spina bifida, parts of the neural tube fail to develop or close properly, causing defects in the spinal cord and in vertebrae. This occurs when bones of the spine do not form properly around a baby’s spine. The exact cause of this defect is not known. However, expert think that genes and environment have an effect. If a mother has one child with this defect, it is thought that another…

Poliomyelitis, better known as the polio virus, is a crippling, and potentially, deadly disease that spreads from person to person. This disease is very contagious, and only infects humans. The virus consists of a RNA genome enclosed in a protein shell called a capsid. There are three serotypes of wild poliovirus have slightly different capsid proteins. In 1789, British physician, Michael Underwood, provided the first clinical description of the poliovirus. He provided a stat, that stated 72…

The cerebrum is the largest part of the brain, while it’s connected with brain function such as thinking and doing actions. There are four sections to the cerebral cortex there is the Frontal lobe that is responsible for reasoning, planning, parts of speech, movement, emotions, and problem solving. Then there is the Parietal lobe, that is responsible for movement, orientation, recognition, perception of stimuli, Then the Occipital lobe that is responsible for visual processing, and the Temporal…
