Overview of the Nervous System

The body's complex network of nerves and cells responsible for receiving and sending information throughout the body.

The central processing unit of the nervous system, including the brain and spinal cord.

The largest part of the brain responsible for functions like thinking, learning, and decision-making.

The part of the brain under the cerebrum that controls balance, coordination, and movement.

Connects the brain to the spinal cord and controls automatic functions like breathing and heart rate.

The ability of the body to maintain a stable internal environment despite external changes.

A system used by the body to maintain homeostasis by responding to internal changes and restoring balance.

The part of the brain that coordinates the nervous and endocrine systems to maintain homeostasis.

The process where the nervous system and endocrine system work together to regulate body functions and maintain balance.

Chemical messengers produced by the endocrine system that travel through the bloodstream to target specific organs and regulate their functions.

The spinal cord acts as a pathway for signals between the brain and the body, and it controls basic reflexes without brain involvement.

The PNS connects the central nervous system to all parts of the body, enabling communication between organs and limbs.

The Somatic Nervous System controls voluntary movements, allowing us to consciously control our muscles.

A neuron is the basic unit of the nervous system, responsible for transmitting signals throughout the body.

The synapse is the gap between two neurons where signals are transmitted from one neuron to the next.
