Climbing fibers

Nerve fibers are processes of nerve cells (neurons), covered with a protective sheath and connecting them to each other or to working organs. The main function of nerve fibers is to conduct stimuli in the nervous system. We perform all actions with the help of various muscle groups or some mechanisms thanks to nerve fibers.

There are three types of nerve fibers: motor, sensory and autonomic. Their functions are hidden in the name. The first are responsible for muscle contraction, the second are responsible for skin and interoreceptive receptors and the perception of internal organs, and the third ensure the functioning of internal organs. The motor fiber, coming from the neurons of the spinal cord, goes to the muscle and causes its muscle contraction. The sensitive ending of this nerve is located in the thickness of the fiber, and not on its surface, as in non-medicinal options. Autonomic fiber transmits information from the body to the nerve node, which ensures the functioning of internal organs in real time. Essentially, autonomic nerve endings provide feedback to the body that allows it to properly direct its natural physiological responses. All regulation of autonomic functions occurs through the parasympathetic nervous system. Nerve fibers and their classification All types of nerve endings conduct impulses at a speed of 120 to 205 m/s. But they differ in length: - short ones have higher speeds; - long ones are slower, as they require greater impulse intensity to travel a significant distance. This only occurs in the case of spasmodic contractions that stimulate the long fibers. The classification of types of nerve processes taking into account their ability to conduct different numbers of impulses (from 1-3 to 70) is called myelination.
