Question

How is the nervous system classified structurally

Answer 1

Well, there is the central nervous system and peripheral nervous system. The central nervous system consists of the brain and spinal chord, and is responsible for the output of signals and processing of sensory etc. signals (ie. systemic control). The peripheral nervous system can be divided into the somatic nervous system, which controls voluntary movement and the autonomic nervous system. The autonomic nervous system can be divided into the sympathetic and parasympathetic branches and is responsible for unconscious gland and organ function. The sympathetic nervous system is responsible for stress responses (such as exercise, fear, emotional duress), the parasympathetic branch is responsible for the control of resting functions (digestion, relaxation and sexual function). I hope that's enough detail. Cheers.

Answer 2

The nervous system is the organized structure of nerve endings and cells called neurons. It runs throughout the body, and it's why we feel and respond to our circumstances, environment and life events the way we do. Anatomists classify the system structurally. It is organized and labeled as a bodily whole divided into two classified systems, one at the center of the system and the other making up its peripheral edges.
