Answer: The nervous system is necessary for the survival of the organism.
Explanation:
The nervous system is the main center of control and coordination of the entire body. It regulates various activities in the body like breathing, movement, thinking, reasoning, feeling emotions, sleep and wake, reproduction, and other necessary functions. The brain and spinal cord are the two chief components of the nervous system. There are many neurons present in the brain. The neurons are the nerve cells that help in communication with the other cells of the body like muscles and gland cells. They receive the signals from all the body parts and direct them to brain for interpretation. Neurotransmitters are the chemical messengers that transmit messages between the neurons, and from neurons to the muscles or other cells of the body.
