Detailed explanation-1: -Your nervous system uses specialized cells called neurons to send signals, or messages, all over your body. These electrical signals travel between your brain, skin, organs, glands and muscles. The messages help you move your limbs and feel sensations, such as pain.
Detailed explanation-2: -The brain is like a computer that controls the body’s functions, and the nervous system is like a network that relays messages to parts of the body.
Detailed explanation-3: -The nervous system transmits signals between the brain and the rest of the body, including internal organs. In this way, the nervous system’s activity controls the ability to move, breathe, see, think, and more. The basic unit of the nervous system is a nerve cell, or neuron.

It receives afferent impulses from sensory receptors located throughout the body and processes the information for distribution to the appropriate cortical area. It is also responsible for regulating consciousness and sleep.
