<P> An axon ( from Greek ἄξων áxōn , axis ) or nerve fiber , is a long , slender projection of a nerve cell , or neuron , that typically conducts electrical impulses known as action potentials , away from the nerve cell body . The function of the axon is to transmit information to different neurons , muscles , and glands . In certain sensory neurons ( pseudounipolar neurons ) , such as those for touch and warmth , the axons are called afferent nerve fibers and the electrical impulse travels along these from the periphery to the cell body , and from the cell body to the spinal cord along another branch of the same axon . Axon dysfunction has caused many inherited and acquired neurological disorders which can affect both the peripheral and central neurons . Nerve fibers are classed into three types -- group A nerve fibers , group B nerve fibers , and group C nerve fibers . Groups A and B are myelinated , and group C are unmyelinated . These groups include both sensory fibers and motor fibers . Another classification , groups only the sensory fibers , and these are grouped as Type I , Type II , Type III , and Type IV . </P>
