The Nervous System

Typically, the nervous system is a biological information highway. The nervous system is responsible for controlling all the biological processes and movements in the body, and can also receive and interpret information by means of electrical signals that are used in this nervous system. It mainly consists of the Central Nervous System (CNS), which is the processing area and the Peripheral Nervous System that detects and sends electrical impulses, which are in turn used in the nervous system.

Mainly the nervous system of a human consists of around a hundred billion nerve cells or neurons. The nervous system is based on anatomical features and can be divided into two parts, which are the central nervous system (CNS) and the peripheral (PNS). While the brain and the spinal cord constitute the central nervous system, the cranial and spinal nerves form parts of the peripheral. The peripheral nerves connect the central nervous system with the sense organs, the organs for vision, hearing, smell, taste and perceptional touch, and other effectors organ like muscles and glands.
