Summary Introduction

To determine:

Differences between the central nervous system and the peripheral nervous system.

Introduction:

The nervous system is found in animal body that helps in the coordination of behavior and transmission of signals between different areas of body. In vertebrates, nervous system is divided into the peripheral nervous system and the central nervous system.

Explanation of Solution

The difference between central nervous system and the peripheral nervous system:

Central nervous system	Peripheral nervous system
1. It contains the brain and the spinal cord.	1. It consists of the sensory nerves and motor nerves that arise from the CNS.
2. Here, the brain and the spinal cord receive information.	2. The cranial nerves carry information to sensory organs and spinal nerves carry information from organs to the spinal cord.
3. This nervous system helps in the coordination of all neural functions.	3. This nervous system helps in the movement of the muscles.
4. This nervous system contains nerve cells and glial cells.	4. It has cranial nerves and spinal nerves.
