In the peripheral nervous system, an efferent nerve fiber is the nerve fiber (axon) of an efferent neuron (motor neuron). It is a long process (projection) extending far from the nerve cell body that carries nerve impulses away from the central nervous system toward the peripheral effector organs (mainly muscles and glands). The opposite direction of neural activity is afferent conduction.
