Detailed explanation-3: -Without the nervous system, humans would not be able to function. Nervous tissue is composed of cells called neurons, which allow the body to convey messages through electrical nerve impulses. Neurons help us make sense of stimulation, control muscle contractions, and coordinate many bodily functions and movements.
Detailed explanation-4: -Central nervous system The nervous system directs our body’s reactions to the world and also controls most of our internal functions, everything from muscle movement and blood vessel dilation to the learning of anatomy and physiology facts.
