The nervous system is responsible for coordinating and controlling entire functions of the body. It handles all the activities of the body and is responsible for various senses humans feel. The nervous system is a highly specialized network system that contains countless neurons, which transmit signals between different parts of the body.
With the help of the neurons, the nervous system is able to control all the activities of the body by transmitting signals or messages from the brain to other parts of the body and vice versa.
The nervous system has two components, the central nervous system and the peripheral nervous system. Together with these two components, other organs that are part of the system include ears, eyes, sensory organs of taste and smell, and sensory receptors located in muscles, skin, joints and other parts of the body.
The central nervous system consists of the brain and spinal cord, and it is responsible for sending, receiving and interpreting information from all parts of the body.
The peripheral nervous system consists of sensory neurons and nerves that connect the central nervous system to hands, arms, legs and feet. It serves as a communication relay between the brain and other parts of the body.
