Trigeminal V sends taste sensation from the anterior two-thirds of the tongue and also controls facial expressions, lacrimal and salivary glands. Accessory XI controls swallowing and monitoring blood pressure in the carotid artery. Abducens VI is a mixed nerve providing taste sensation from the posterior one-third of the tongue, controlling swallowing and muscles of the neck. Olfactory I transmits light and images from the eyes to the visual cortex. Oculomotor III predominantly controls eyelid movements such as blinking. Vestibulocochlear VIII is a sensory nerve functioning in hearing and equilibrium. Trochlear IV is a sensory nerve situated immediately superior to the nasal cavity. Hypoglossal XII is a complex nerve controlling digestive, respiratory, and cardiovascular functions. It is also the only nerve that descends below the neck. Glossopharyngeal IX controls the tongue movement during swallowing and speech. Facial VII controls the lateral movement of the eye. Optic II is a sensory nerve functioning in hearing and equilibrium. Vagus X is the largest cranial nerve, innervating the forehead, maxilla, and the mandible.

Vagus nerve b. Accessory nerve c. Hypoglossal nerve d. Abducens nerve 9. Which cranial nerve signals the lens of the eye to change its shape as the distance from an object changes, causing light to focus on the retina? a. Optic nerve b. Oculomotor nerve c. Facial nerve d. Trigeminal nerve 10. You have a cavity in one of your upper teeth and you hear the dentist tell the dental assistant, "We're going to have to extract number 14 (the first molar on the left side)."... Which branch of the trigeminal nerve will the dentist need to block in order to deaden the pain of extraction for tooth #14? a. Ophthalmic branch b. Maxillary branch c. Mandibular branch 11. Recall that the structures responsible for detecting sound lie within the temporal bone... The vestibulocochlear nerve carries information about hearing to the temporal lobe of the brain for interpretation... Through which opening in the temporal bone does the vestibulocochlear nerve pass?
