What is myelin function?

neurons in the central and peripheral nervous system send signals to different areas of the brain and body, changing responses to behavior and physiological processes. These electrochemical signals are sent down Axon, long, thin, cylindrical structure of the neuron, which is associated with its cellular body or soma. The surrounding axon is an insulating material called myelin. The myelin function is to protect the axon by creating a myelin sheath and ensuring that the signals are sent quickly and efficiently. While some parts of the axon are closed or myelinated, other areas are left unpacked or unmyelined, depending on which cell produces myelin. The primary function of myelin pockets is to protect Axon and help in axonal fire by preventing mutual interference. It appears under the cerebral peel, white mass whitish look due to myelin vagina.

cells produced by myelin are called gli -cells. There are two different categories of glial cells called macroglial and microglialof it. Although there are several cells that fall into the macroglial category, two cells that participate in the production and function of myelin chips are called oligodendrocytes and Schwann cells.

In the central nervous system, oligodendrocytes of myelin vagina around the axons are formed, while Schwann's cells help in the production of myelin pockets around axons in the peripheral nervous system. Oligodendrocytes and Schwann cells form myelin vagina by wrapping around the axon; However, Schwann's cells wrap only around the axon segments and leave small gaps between the called Ranvier nodes. Unlike Schwann's cells, myelinization of oligodendrocytes expands to more than just one axon and the only oligodendrocyte can contribute to myelinating several adjacent axons.

The function of myelin is very important, and this is the most obvious in patients suffering from multiple sclerosis. Scattered skLerosis is a disorder that occurs when an individual's immune system attacks myelin vagina surrounding the axons in the central nervous system and deteriorates them. In clinical examination, these areas seem to be hardened and damaged. As a result, patients with this neurological disorder suffer from numerous disorders that affect motor and sensory functions.
