central nervous system
The Central Nervous System or CNS is the center control of the entire nervous system. It is composed of the brain, brainstem and spinal cord. The peripheral nervous system connects the central nervous system to the rest of the body.
Brain
The brain is the executive control of the entire nervous system. Crainal nerves run directly from the brain to various sense organs and face muscles, and vital organs. One of these nerves is the vagus nerve which handles the function of some vital organs.
Brainstem
The brainstem connects the brain to the spinal cord.
Spinal Cord
The spinal cord is like a hub to which most nerves of the peripheral nervous system are attached. There are 31 spinal nerves attached to the spinal cord.
