NEET BIOLOGY

Detailed explanation-1: -The main function of nervous tissue is to receive stimuli and send signals to the brain and spinal cord. These signals are sent to the muscles via the nerves.

Detailed explanation-2: -The nervous system has two main parts. Each part contains billions of cells called neurons, or nerve cells. These special cells send and receive electrical signals through your body to tell it what to do.

Detailed explanation-3: -First, the basic functions of the nervous system are sensation, integration, and response.

Detailed explanation-4: -The nervous system uses tiny cells called neurons (NEW-ronz) to send messages back and forth from the brain, through the spinal cord, to the nerves throughout the body. Billions of neurons work together to create a communication network. Different neurons have different jobs.

Detailed explanation-5: -Neurons send and receive electrical signals to communicate with each other in the nervous system and with other types of cells in the body, particularly muscles. At one end, neurons have branch-like projections called dendrites that allow them to receive signals.
