Every nerve consists of a collection of nerve fibers, each of which arises from a nerve cell body or neuron and can also be classified as afferent or efferent in nature. Nerve fibers conduct impulses in only one direction. Most of the major peripheral nerve trunks contain intermingled afferent and efferent fibers, and the nerves are therefore called mixed nerves. The sensory (afferent) nerve fibers receive information from sensory receptors (specialized cellular structures) with which they connect or from the endings of the nerve fibers themselves.
