The Olfactory Nerve is the first of the Twelve Cranial Nerves. It consists of both afferent and efferent sensory fibers. The word Afferent means toward the centre, as in from a peripheral area of a limb to the central nervous system. The Olfactory Cells contain sensory nerve fibers that are alerted to the sense of smell. 2  There is a refractory period for each cell so certain areas of the Olfactory mucosa are stimulated each time a new smell enters the Nasal Cavity.
