About Peripheral Nerves
Your peripheral nerves are the ones outside your brain and spinal cord. The peripheral nervous system acts as a connector between the central nervous system (which is your brain and spinal cord) and the rest of your body. Peripheral nerves that connect the brain and spinal cord to muscles to stimulate movement are called motor nerves. Those that connect the brain and spinal cord to your skin and allow are called you to feel pain and other sensations are called sensory nerves.
When we decide to move, the brain sends a message to the spinal cord and from there the nerves carry the message to the necessary muscles to make them contract and produce movement. Similarly when we touch an object, sensory information is carried from the skin to the spinal cord and then to the brain so that we can make sense of that information.
Peripheral nerve disorders distort or interrupt messages sent between the brain and the rest of the body.
Unlike the brain and spinal cord, peripheral nerves can regrow after an injury, but surgery is often required to reconnect the peripheral nerves so that movement and sensation can be restored.
