The term of the nervous system is 'Neural', which is a six letter word. The nervous system is a complex network of cells, tissues, and organs that coordinate the body's responses to internal and external stimuli. It is composed of the central nervous system, which includes the brain and spinal cord, and the peripheral nervous system, which includes the nerves and ganglia outside of the brain and spinal cord. The nervous system is responsible for controlling and coordinating bodily functions, such as movement, digestion, and respiration.
