# Cranial Nerves This document describes the different cranial nerves, their functions, and whether they are sensory, motor, or both. ## Cranial Nerve Table | # | Name | Function | Sensory | Motor | Both | |---|---|---|---|---|---| | I | Olfactory | Controls sense smell | | | | | II | Optic | Controls vision (from retina) | | | | | III | Oculomotor | Controls eye muscle (pupil) | | | | | IV | Trochlear | Down and out movement of eye | | $\surd$ | | | V | Trigeminal | Sensory info from face, ear, neck, and muscles for chewing | $\surd$ | $\surd$ | | | VI | Abducens | Outward movement of eye | | $\surd$ | | | VII | Facial | Facial expressions, swallowing | $\surd$ | $\surd$ | | | VIII | Acoustic | Sensory info from ears | $\surd$ | | | | IX | Glossopharyngeal | Swallowing, sensory info lungs & stomach | $\surd$ | $\surd$ | | | X | Vagus | Swallowing, sensory info lungs/stomach | $\surd$ | $\surd$ | | | XI | Spinal Accessory | Neck muscles | | $\surd$ | | | XII | Hypoglossal | Tongue and some neck movement | | $\surd$ | | **Note:** The table shows which nerves are responsible for sensory, motor, or both sensory and motor functions. The symbols ($\surd$) indicate whether the nerve is involved in a particular function. The table also includes a short description of the function of each nerve.
