Nervous system - a set of specialized cells, remaining in complex functional and structural relationships, responsible for controlling the body's activity. The nervous system is able to detect specific changes in the environment and, therefore, trigger an appropriate response of the body.

It is built of nerve cells and glial cells. From the histological point of view, the collection of nerve cells is sometimes called the nerve tissue, and the collection of glial cells - the glial tissue

However, neural and glial cells are not separated from each other, but together they form a compact mass, hence many authors believe that the separation of the nervous system into two tissues is incorrect, unreal and therefore accept the existence in the nervous system of only one nerve tissue that they form both neural and glial cells

Nerve cells are characterized by the ability to produce, transmit to other cells and receive specific signals from other cells, as well as the ability to convert this signal when it is transmitted from the cell to the cell.

The importance and complexity of the structure of the nervous system increases with the evolution of evolutionary organisms. First of all, along with evolutionary development, the complexity of those parts of the nerve cell network that modulate signals transmitted between the starting point and the end point increases. As a result, more developed organisms are characterized by richer behavioral activity and greater freedom of shaping their reactions, going beyond the physiological automatism of the stimulus-reaction.
