Spinal nerves

A set of 31 pairs of nerves that connect to the spinal cord. Spinal nerves emerge in 2 rows from either side of the spinal cord and leave the spine through gaps between adjacent vertebrae. The nerves then branch out to supply all parts of the trunk, arms, and legs with sensory and motor nerve fibres. Disc prolapse may lead to pressure on a spinal nerve, causing pain. Injury to a nerve may lead to loss of sensation or movement in the area supplied by the nerve. (See also nerve injury; neuropathy.)
