What does the spinal cord do?

The brain and spinal cord are your body’s central nervous system. The brain is the command center for your body, and the spinal cord is the pathway for messages sent by the brain to the body and from the body to the brain.

The peripheral nervous system is the network of nerves strands that branch off from the left and right sides of the spinal cord through openings between each vertebra on the spinal canal. These nerve pairs spread throughout your body to deliver commands from your brain and spinal cord to and from parts of your body.

The central nervous system and peripheral nervous system work together to allow your brain to control your body’s many functions, which includes 3 important areas (Diagram):

Motor Functions - directs your body’s voluntary muscle movements.

Sensory Functions – monitors sensation of touch, pressure, temperature and pain.

Autonomic Functions – regulates digestion, urination, body temperature, heart rate, and dilation/contraction of blood vessels (blood pressure).
