Fibers Nerve Myelin

Nerve myelin fibers (or neurofibromyelin) are long protein strands that cover nerve cells and help transmit electrical signals between them. These fibers play an important role in the nervous system and can be damaged in various diseases such as multiple sclerosis, Parkinson's disease and others.

Nerve myelin fibers range from 2 to 10 micrometers in length and are composed of several proteins, including myelin, which is a major component of the nerve cell sheath. Myelin acts as an insulator, preventing electrical current from spreading along the entire length of the fiber.

Disturbances in myelin synthesis or its destruction can lead to various diseases, such as myelopathy, myasthenia gravis, Guillain-Barré syndrome and others. With myelopathy, for example, there may be a decrease in the speed of transmission of nerve impulses, which leads to muscle weakness and impaired coordination of movements.

Various methods, such as magnetic resonance imaging (MRI), positron emission tomography (PET) and electromyography, are used to diagnose diseases associated with disturbances in the synthesis and destruction of myelin. Treatment may include medications to improve myelin synthesis and protection from destruction, as well as physical therapy to improve muscle function.

In general, the study of nerve myelin fibers is important for understanding the mechanisms of the nervous system and developing new methods for treating diseases associated with their disruption.

Myelinated nerve fibers are often called the “first prefrontal neurons”; they are fibrillar intermediate bundles of axons that form the basis of acetylcholine and adrenergic neuron fibers of the nervous system. Myelincytiary complex, a structure formed due to damage to the myelin layer of a neuron and displacement of the nucleus in neuronal cancers that negatively affect speech. These cell types contain short peptides containing oligopeptides.

These structures are formed predominantly in the early classes of brain structures, that is, in the prenatal period. Subsequently, they must find a place in the front part of the brain and are involved in many functions, including the growth of the fetus, the development of the front part of the skull, the development of the eye with cells in them, the development of the cerebral cortex through the formation of three pairs of thoracic vertebrae, and the olfactory senses. They also play an important role in maintaining mood regulation (for example, in the development of schizophrenia).

Fibers are usually considered as a complex of several cells. Depending on the biochemical designation used, the term fiber can refer to any multilayered population of cells found in specialized areas of the central nervous system, such as the nerve spindles, medulla, anterior hypothalamic
