Peripheral nerves - Definition

December 2016


Definition

The body's many peripheral nerves are what connects the entire central nervous system, produced by the brain and spinal cord, to the various muscles and organs of the body. They make up the peripheral nervous system, as opposed to the aforementioned central nervous system. They are simultaneously motor nerves (controlling the contraction of different muscles) and sensory nerves (relaying sensory information from the innervated area of the body to the central nervous system). The majority of nerve pain (neuropathy) involves the peripheral nerves. Depending on the number of damaged nerves or the location of the damage, different terms are used, such as mononeuropathy when only one nerve is affected, polyneuropathy when several are affected, or polyneuritis where the longest nerve fibers are affected.
