Detailed explanation-1: -Another example of a biological system is the nervous system. A human central nervous system is comprised of the brain, the spinal cord, and the peripheral nervous system. Its main function is for coordinating actions by transmitting signals to and from different parts of the body.

Detailed explanation-2: -The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

Detailed explanation-3: -Your nervous system is your body’s command center. Originating from your brain, it controls your movements, thoughts and automatic responses to the world around you. It also controls other body systems and processes, such as digestion, breathing and sexual development (puberty).

Detailed explanation-4: -Like other systems in the body, the nervous system is composed of organs, principally the brain, spinal cord, nerves, and ganglia. These, in turn, consist of various tissues, including nerve, blood, and connective tissue. Together these carry out the complex activities of the nervous system.
