Parasympathetic fibers

There are always two types of nerve fibers in the human body - sympathetic and parasympathetic. Fibers Parasympathetic is one of the terms to describe the latter type of nerve fibers.

Although parasympathetic fibers are generally considered inactive, they play an important role in maintaining homeostasis in the body. They regulate the secretion of hormones and other biologically active substances, such as insulin, acetylcholine and serotonin. Under normal conditions, parasympathetic fibers influence metabolic processes and sleep, and also control the functioning of the intestines and gastrointestinal tract. However, the abnormal activity of these fibers can lead to various diseases such as diarrhea, abdominal pain and insomnia. In addition, disturbances in the functioning of parasympathetic fibers can cause various allergic reactions and even asthmatic attacks. Therefore, the role of parasympathetic fibers in the normal functioning of the body and the treatment of many diseases is an important and relevant topic in the field of neurophysiology and medicine in general.
