The Parts
Of
Nervous system
I.
-The nervous system is a very complex system in the body. It has many, many parts. The nervous system is divided into two main systems, the central nervous system (CNS) and the peripheral nervous system. The spinal cord and the brain make up the CNS. Its main job is to get the information from the body and send out instructions. The peripheral nervous system is made up of all of the nerves and the wiring. This system sends the messages from the brain to the rest of the body. -The peripheral nervous system consists of the nerves that lie …show more content…

Sympathetic and Parasympathetic Nervous System
The autonomic system regulates the involuntary body functions like respiration, heartbeat, blood flow and digestion. It is further subdivided into the sympathetic nervous system which regulates your flight-or-fight responses, and the parasympathetic system that helps regulate various normal functions of the body, for example, sexual arousal, salivation, lacrimation (shedding tears), urination, digestion, and defecation. Functions of the parasympathetic nerves include constriction of eye pupils, increase in secretion of saliva, increased digestion, decrease in heartbeat, etc. The sympathetic nerve functions involve dilation of eye pupils, sweating, production of goose bumps, decrease in digestion, etc. One of the important nerves, the vagus nerve is divided into sympathetic and parasympathetic nerves.

The sensory system is also a part of the nervous system. Sensory systems for vision, hearing, somatic sensation (touch), taste and olfaction (smell) work with the help of the sensory receptors, neural pathways and certain parts in the brain that help process sensory information. When you feel cold or hot, it is the sensory neurons that are doing their work. The motor neurons are reactors, that help the body react to different environment. For example, the immediate pulling away of your hand when you touch a hot stove
