Nervous system
(
lat.
systema nervosum), a morphofunctional set of individual neurons and other structures of the nervous tissue of animals and humans, uniting the activities of all organs and systems of the body in its constant interaction with the external environment. The nervous system perceives external and internal stimuli, analyzes and processes incoming information, stores traces of past activity (memory mechanisms) and accordingly regulates and coordinates body functions. The activity of the nervous system is based on a reflex associated with the spread of excitation along reflex arcs and the process of inhibition. The nervous system is composed primarily of nervous tissue, the basic structural and functional unit of which is the neuron.[1]
