From Wikipedia, the free encyclopedia. Sensory neurons are nerve cells that transmit sensory information (sight, sound, feeling, etc.). They are activated by sensory input, and send projections to other elements of the nervous system, ultimately conveying sensory information to the brain or spinal cord.rom Wikipedia, the free encyclopedia.

The area of attachment of a cranial nerve to the surface of the brain is termed itssuperficial or apparent origin. The fibers of the nerve can be traced into the substance of the brain to a special nucleus of gray substance. The motor or efferent cranial nerves arise within the brain from groups of nerve cells which constitute their nuclei of origin. The sensory or afferent cranial nerves arise from groups of nerve cells outside the. brain; these nerve cells may be grouped to form ganglia on the trunks of the nerves or may be situated in peripheral sensory organs such as the. nose and eye. The central processes of these cells run into the brain, and there end by arborizing around nerve cells, which are grouped to. formnuclei of termination.
