The cranial nerves can be classified as special sensory, (primarily) motor, or mixed sensory and motor. Olfactory Nerve (N I) The olfactory nerve is a special sensory cranial nerve that is responsible for the sense of smell.
For a complete list of the named nerves of the body, see Table 14. Depending on their function, nerves are known as sensory, motor or mixed. Sensory nerves, or afferent nerves, carry information from the periphery of the body to the brain and spinal cord. Sensations of heat, cold, pressure and pain are conveyed by the sensory nerves. Motor nerves, or efferent nerves, transmit impulses from the brain and spinal cord to the periphery, especially the muscles. Mixed nerves are composed of both motor and sensory fibers, and transmit messages in both directions.
