Central nervous system

critical this system is to the body of a human, it is critical that research goes into compounds and chemicals that can potentially pose a risk to this system. Since mercury is a toxic element to human beings (FDA, 2015), it is important to question the introduction of dental amalgam from 150 years ago and ask if this is something that can continue to be used. Dental amalgam has been shown to cause damage to the central nervous system, which as shown above, the central nervous system is crucial…

What is the central nervous system? It’s a system which consists of the nerves in the brain and spinal cord. It gathers information about and reacts to internal and external stimulus. Don’t Shoot the Messenger Much of the CNS is made up of neurons. Each neuron has a cell body, which includes a soma with a nucleus, a nucleolus, a cytoplasm called the perikaryon, and wide branching extensions called dendrites. Dendrites are like antennae which receive signals from other neurons or body cells.…

Background MS (MS) is an auto immune disease which affects neurons of the central nervous system. A neuron consists of three main parts: an axon, dendrite, and a cell body. The axon is usually myelinated with a substance known as the myelin sheath, created by oligodendrocytes. This consists of twenty percent protein and eighty percent lipid. Each oligodendrocyte creates enough myelin to wrap around several axons. The periodic gaps between the neurons are known as nodes of Ranvier, where the…

Bullying primarily affects the CNS (central nervous system) and PNS (peripheral nervous system) of an individual which activates the hormonal glands. Therefore it will start to secrete certain stress hormones in adequate amount that will have negative effect on behaviour of the child. Mental and physical stressors, for example, being the objective of tormenting, actuate the anxiety framework focused on the hypothalamic-pituitary-adrenal (HPA) hub (Dallman et al., 2003; McEwen and McEwen, 2015).…

Parkinson's disease is a whole deal issue of the central nervous system that for the most part impacts the motor system. [1] The symptoms all things considered proceed bit by bit after some time. Right on time in the contamination, the most apparent are shaking, rigid nature, progressiveness of advancement, and issue with walking. [1] Thinking and behavioral issues may similarly happen. Dementia gets the chance to be ordinary in the impelled periods of the illness. Despairing and uneasiness are…

Another situation where the central nervous system provides a feedback loop is when there is a high concentration of carbon dioxide in the bloodstream. This event was simulated during the re-breathing exercise. Unlike hyperventilation, where the subject had a long breath-hold and a small carbon dioxide composition, re-breathing had the shortest duration and the highest percent of carbon dioxide. The test subject was able to hold her breath for only 27 seconds. Meanwhile, her CO2% increased from…

volume of the mammalian central nervous system comprises of an extracellular matrix that includes proteins, proteoglycans, and glycosaminoglycans (Bignami A et.al 1993). Evolving evidence indicates that the organization and composition of this matrix change throughout the course of normal aging, during neurodegenerative diseases and following central nervous system injury and that these modifications influence a diverse range of cellular behaviors. The central nervous system extracellular matrix…

Rabies (from the Latin word “madness”) has been recognized for over four thousand years. The first record of rabies dates back to 2300 B.C. in the Babylonian city of Eshnunna when dog owners were forced to pay a fine for causing the deaths of other people. Since then, many notable writers and philosophers such as Homer, Democritus, and Aristotle have also recorded rabies, mostly through cases of canine rabies (or rabies received through a rabid dog). During the 16th century, Girolamo Fracastoro,…

(cerebrospinal fluid “CSF”). CSF circulates inside the central nervous system through the ventricular part of this system and is finally absorbed into the bloodstream. Thus, the central nervous system literally floats in a cushion of CSF.1 CSF function CSF is going under continuous circulation and as a result the central nervous system literally floats in a cushion of CSF. This cushion protects the two major areas of the central nervous system…

In the year 1868, a disease that affects the central nervous system was identified. In the studies of Jean-Martin Charcot, he named the disease that would eventually become known as “Multiple Sclerosis”. Multiple Sclerosis, or MS, is an autoimmune disease that makes your body attack the covering of the axons of the nerves, known as the myelin sheath, in the brain and along the spinal cord. This can cause a disruption in the communication between the brain and the rest of the body. ("Multiple…
