Nervous System

        Nervous System

The nervous system includes the brain, spinal cord, and a complex network of nerves. This system sends messages back and forth between the brain and the body.

The brain is what controls all the body's functions.

The nervous system is the body's communication network, responsible for coordinating bodily functions through electrical and chemical signals.

It's divided into the central nervous system (brain and spinal cord) and the peripheral nervous system (nerves and ganglia connecting the body to the CNS).

This system enables us to perceive the world, think, learn, remember, and move, while also regulating basic functions like breathing and heartbeat.

The central nervous system is made up of the brain and spinal cord,

The brain controls how we think, learn, move, and feel.

The spinal cord carries messages back and forth between the brain and the nerves that run throughout the body.

Key Components:

Brain:

     The central control center for processing information and coordinating bodily functions.

Spinal Cord:

            A long, slender cord that connects the brain to the rest of the body, transmitting signals.

Nerves:

      A network of nerve cells (neurons) that transmit signals throughout the body.

Functions:

Sensory Perception:

                   Receiving information from the environment through sensory organs.

Motor Control:

              Directing movement and muscle contractions.

Cognitive Functions:

                    Encompassing thoughts, learning, memory, and consciousness.

Homeostasis:

            Regulating internal body conditions, such as temperature and blood pressure.

In essence, the nervous system is the body's command center, constantly receiving, processing, and responding to information, enabling us to interact with the world and maintain our internal balance.
