peripheral nerve
Body's outlying cables
A peripheral nerve is any nerve outside the brain and spinal cord.
These nerves branch throughout the body, carrying signals between the central nervous system and limbs, organs, and skin.
They control movement, sensation, and automatic functions like heart rate and digestion: The surgeon carefully avoided the peripheral nerves during the procedure.
