peripheral nerve

Peripheral nerves are part of the nervous system outside the brain and spinal cord. They act like electrical cables, transmitting signals between the central nervous system and the rest of the body. These nerves carry sensory information (like touch, pain, or temperature) from the skin and muscles to the brain, and motor commands from the brain to muscles to control movement. Composed of bundles of nerve fibers surrounded by protective layers, peripheral nerves enable sensation and coordination. Damage to these nerves can cause numbness, weakness, or pain, highlighting their crucial role in everyday bodily functions.
