Human Central Nervous System | ClipArt ETC

This human anatomy ClipArt gallery offers 265 illustrations of the central nervous system, including external and dissected views of the brain and spinal cord.

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.
