Nervous System

The nervous system is a complex network of nerves and cells that transmit signals between different parts of the body. It is responsible for coordinating and controlling the body's activities.

Parts of the Nervous System

The nervous system is divided into two main parts:

• Central Nervous System (CNS) - This includes the brain and spinal cord. It is the control center of the body.
• Peripheral Nervous System (PNS) - This consists of the nerves that extend from the CNS to the rest of the body. It helps in transmitting information to and from the CNS.

Functions of the Nervous System

The nervous system performs several important functions, including:

• Receiving and Processing Information - It receives information from the senses and processes it to make sense of the world.
• Controlling Body Movements - It coordinates and controls voluntary and involuntary movements of the body.
• Regulating Internal Functions - It regulates functions such as heart rate, breathing, and digestion to maintain homeostasis.

Study Guide

Here are some key points to remember about the nervous system:

1. The central nervous system consists of the brain and spinal cord.
2. The peripheral nervous system includes all the nerves outside the brain and spinal cord.
3. The nervous system helps in controlling and coordinating body activities.
4. It receives and processes information from the environment and the body's internal systems.
5. It is responsible for both voluntary and involuntary actions of the body.
