<Tr> <Th> Axon </Th> </Tr> <Tr> <Td> Dendrite Soma Axon Nucleus Node of Ranvier Axon terminal Schwann cell Myelin sheath </Td> </Tr> <P> An axon (from Greek ἄξων áxōn, axis), is a long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses away from the neuron's cell body . Axons are also known as nerve fibers . 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 electrical impulse travels along an axon 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--A delta fibers, B fibers, and C fibres . A and B are myelinated and C are unmyelinated . </P> <P> An axon is one of two types of protoplasmic protrusions from the cell body of a neuron; the other type is a dendrite . Axons are distinguished from dendrites by several features, including shape (dendrites often taper while axons usually maintain a constant radius), length (dendrites are restricted to a small region around the cell body while axons can be much longer), and function (dendrites receive signals whereas axons transmit them). All of these rules have exceptions, however . </P>
