Motor nerve

Motor nerve cells

A motor nerve is a nerve that carries command information out of the central nervous system (CNS) and toward effectors (muscles or glands) that will execute the commands. It is an enclosed, cable-like bundle of efferent nerve fibers (the axons of motor neurons) in the peripheral nervous system (PNS). These fibers link processing circuits in the CNS to the body parts that will carry out the CNS's decisions (conscious and unconscious). Motor nerves are often paired with sensory nerves, which are bundles of afferent nerve fibers that travel from the PNS to the CNS.
