Excitation Coordinated

Coordinated excitation is one of the important mechanisms of excitation, which ensures coordinated reactions of various organs and tissues in the body in response to external stimuli. In physiology, excitation is the spontaneous occurrence of an electrical impulse at the presynaptic end of a receptor or tissue. Excitation is an integral part of complex reflex acts (for example, acts of excitation when walking). The essence of excitation is that under the influence of a stimulus, one or another type of nervous excitation occurs in the precentral parts of the cerebral hemispheres. It spreads throughout the peripheral part: muscles, blood vessels and other tissues, that is, it can cause muscle contraction, changes in the lumen of blood vessels, the formation of sputum and other important physiological effects.
