Illustration of the reflex action of an animal. SE is the sensory nerve-ending. A stimulus passes through the sensory nerve-fiber SF to a nerve-cell SC in the ganglion of a dorsal or afferent (convey towards the center) root (DR) of a spinal nerve. The fiber divides in the spinal cord (SP C) where the message is relayed to an internuncial nerve-cell (A). MO is motor nerve-cell, VR is ventral or efferent nerve, ME is nerve plate, and MU is muscle fiber.
