vestibulocochlear nerve.
This is the largest cranial nerve. It provides sensory information from the face, forehead, nasal cavity, tongue, gums and teeth (touch, and temperature) and provides somatic motor innervation to the muscles of mastication or chewing. The auditory nerve and the vestibular nerve, which carries balance information from the semicircular canals to the brain, join together as they pass through the bony canals of your skull. Together, they are called the 8th cranial nerve, or the Vestibulocochlear nerve. 1. Olfactory. This is a type of sensory nerve that contributes in the sense of smell in human being. These basically provide the specific cells that are termed as olfactory epithelium. It carries the information from nasal epithelium to the olfactory center in brain. These roots become nerves that innervate (transmit nerve impulses to) muscles and organs throughout the body. Twelve pairs of cranial nerves transmit from special sensory receptors information on the senses of balance, smell, sight, taste, and hearing. Cranial nerves also carry information from general sensory receptors in the body, mostly from the head region. There are total 12 pairs of cranial nerves that originate from our brain and brain stem. Each of them carries different functions related to different senses of body. Apart from sensory functions there are also some that work as motor nerves or mixed nerves. Here is a brief description of 12 cranial nerves. The sensory portion of thisnerve carries sensory information for taste from the anterior 2/3 of the tongue and the palate.Lesions of the facial nerve cause facial paralysis that is usually unilateral. There is also a loss oftaste sensation in the anterior 2/3 of the tongue and decreased salivation. 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. The 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.
