6. Hearing and Balance: 7. Major functions include "taste" of posterior 1/3 of tongue (glosso). controls pharyngeal muscles of swallowing, controls parotid salivary gland, monitors CO2 levels, 02 levels and blood pressure in carotid artery. 8. Wanderer Only cranial nerve to extend beyond head and neck to the thorax and abdomen. Multiple functions including swallowing and speech production; taste on posterior of tongue and pharynx; monitoring blood pressure, pH, CO2 levels, and 02 levels in arch of Aorta; innervation of heart, lungs, and abdominal viscera. digestive system heart lungs kidney 9. Medullary branch - motor to pharynx, soft palate and larynx, (control vocal cords and speech production) Spinal branch - Motor to sternocleidomastoid and trapezius (move head and neck) Vocal cords 10. Voluntary control of skeletal muscles of tongue (sticking out your tongue, helps in speech, swallowing)Identify which of the cranial nerves are responsible for each of the following: 3. Smelling: 4. There are 4 cranial nerves associated with your eyes. One for "seeing" and 3 for moving the eye. Name these. 5. There are two cranial nerves you associate with the face a. One is the major face and head "sensor" and has three branches (V1 = ophthalmic branch, V2 = maxillary branch, and V3 = Mandibular branch) This nerve also provides motor control over chewing muscles. b. The second is the chief motor nerve to the face for facial expressions. It has five main branches. It also "tastes" the anterior 2/3 of the tongue and controls tear and submandibular and sublingual salivary glands. Temporal Zygomatic Buccal Mandibular Cervical
