Olfactory Nerve (N I). The olfactory nerve is a special sensory cranial nerve that is responsible for the sense of smell. The receptors of these neurons are found in the olfactory epithelium and the axons pass through the cribriform plate of the ethmoid bone.he sensory nerves carry general sensory information from the pharynx and the soft palate. Sensory neurons also convey information from taste and general sense receptors in the posterior one-third of the tongue, and from receptors in the carotid sinus that convey information about pressure and blood gases.
