Peripheral Nerve Conditions
The peripheral nervous system is a network of 43 pairs of motor and sensory nerves that connect the brain and spinal cord to the entire human body. The most common conditions of the peripheral nerves involve the median nerve and sciatic nerve. The median nerve provides sensation to the thumb, first, second, third, and part of the fourth finger. The sciatic nerve is the largest single nerve in the body, extending from the lumbar spine and buttocks down the back of the thigh.
