WebA motor nerve is a nerve that transmits motor signals from the central nervous system (CNS) to the muscles of the body. This is different from the motor neuron, which includes a cell body and branching of dendrites, while the nerve is made up of a bundle of axons. WebA sensory nerve, or afferent nerve, is an anatomic term for a nerve which contains exclusively afferent nerve fibers. [1] Nerves containing also motor fibers are called mixed.
