A nerve is an enclosed, cable-like bundle of axons (nerve fibers, the long and slender projections of neurons) in the peripheral nervous system. A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the axons to peripheral organs. Afferent nerves conduct signals from sensory neurons to the central nervous system, for example from the mechanoreceptors in skin. 2  Efferent nerves conduct signals from the central nervous system along motor neurons to their target muscles and glands.
