axon /ak″son/ [Gk, axle] , an extension, usually long and slender, of a neuron capable of conducting action potentials or self-propagating nervous impulses. Axons can conduct impulses over great distances away from the cell body. Only ends of axons (terminals) can release neurotransmitters and stimulate other neurons/effectors. Compare dendrite. See also action potential, neurotransmitter.
