what is around axons
An axon (from Greek á¼Î¾ÏÎ½ Ã¡xÅn, 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.
