What Is Myelin?

Myelin is a part of the nervous system, it is the lining of the nerve fibers whose purpose is to protect and insulate the neurons. Myelin is helpful in the fast and accurate transmission of electrical currents that help transmit data from one nerve cell to the next one. If myelin becomes damaged it can bring a number of health problems, one of them being multiple sclerosis.

Nerves function much like electricalwire. Current must pass through a path in order to get fromone point to another. The current must be able to travel without any kind of deterioration or corruption in the signal. Myelin functions much like the plastic insulation that surrounds a wire -- which is the nerve. Myelin also functions as an aid in ensuring the speedy transmission of the signal.

Myelin is always composed of lipids of proteins but myelin also functions differently depending on which part of the nervous system it's being used. For example, the human body has a peripheral nervous system (PNS) that branch from the spinal cord. Its function is to bring information that is related to sensory input. The brain's central nervous system (CNS), on the other hand, decides how to act on the input given by the PNS. These two systems synthesize myelin in its own way. This also means that it produces different kinds of complications.

Any problems with the myelin that is contained in the nerve fibers results in problems in the delivery of information. This could result in the slower transmission of nerve impulses, which means slower reaction to stimuli or even confusion when exposed to stimuli.
