Afferent system

The afferent nervous system is the part of the nervous system that is responsible for converting the energy of stimulation and conducting nerve impulses to the central nervous system. This system plays an important role in regulating all body functions, including breathing, circulation, digestion and other processes.

The afferent nervous system consists of many nerve fibers that transmit information from peripheral organs and tissues to the central nervous system. These nerve fibers are called afferents because they carry information about external stimuli and internal processes in the body.

One of the main functions of afferent nerve fibers is the conversion of irritation energy that occurs in external organs and tissues into nerve impulses. For example, when we touch an object or smell something, nerve fibers transmit information about the stimulus to the central nervous system, where it is processed and interpreted.

In addition, afferent nerve fibers are also responsible for conducting nerve impulses from external organs and tissues to the central nervous system. This allows the central nervous system to receive information about the state of the body and regulate its functions.

Thus, the afferent nervous system plays a key role in the functioning of the body. It converts the energy of stimulation into nerve impulses, which are transmitted to the central nervous system for processing and interpretation, and also conducts nerve impulses from external organs and tissues to regulate various body functions.

Afferent nerves (nerves that carry excitation to the central nervous system from organs and tissues) form the first nerve system, which includes the roots of the cranial and spinal nerves. Along the entire length of the afferent nerve there is a bundle of myelinated nerve fibers - which is a nerve fiber surrounded by neurolemmocytes that prevent its death and conduction. The afferent nerve does not have its own nerve that would carry impulses from the periphery through the central nervous system to certain areas of the brain. This nerve crosses in close physical contact with fibers of the opposite direction (centripetal) of other parallel nerves in the general cavity of the brain or nerve roots. It is believed that the principle of sharing nerve fibers provides a high degree of synchronization of activity between afferents and centrobe
