The Nervous System - The Master Controlling System

The master controlling system of the body is known as Nervous system. Nervous System is communication system of the body which trans-locate messages from one part of the body to the another. The nervous system controls and co-ordinate all the essential body functions and activities.

Functions of the Nervous System-The three main functions of the Nervous Systems are-

1. Sensory Function
2. Integrative Function
3. Motor Function

Sensory Function- Nervous systems have a millions of sensory receptors which helps in monitoring of changes inside and outside of the body. This changes are termed as Stimuli and the gathered information is called sensory input.

 Integrative Function- After receiving the sensory input the Nervous system process and interprets the received information and responds accordingly. The Nervous system's this process is known as Integration.

Motor Function- The Nervous system sends information to the various part of the body so that there  is movement in various parts of the body such as muscular contraction or glandular secretion.

The Nervous system is classified into two types on its structural arrangements these are:

1. Central Nervous System- The central nervous system of the human body consists of  the brain and the spinal cord. These two parts are the controlling part of the  nervous system, they act as controller of the body function, they also convey and interprets the various commands to the various tissues and body parts. CNS receives the various stimuli from the body parts and also directs the body parts to respond.

2. Peripheral Nervous System- The Peripheral Nervous system is a web like structure which are distributed to the various parts of the body. They mainly collects the responses from the various part of the body and transfer them to the CNS. They are classified to Cranial and Spinal Nerves.
The Cranial nerves carry to and fro information from Body parts to brain and vise-versa. The Spinal nerves carries to and fro information from Body parts to spinal cord and vise-versa.
