Difficuly with chewing or an inability to chew might result from damage to the a. vagus nerve b. trochlear nerve. c. hypoglossal nerve. d. trigeminal nerve. e. vestibulocochlear nerve. Motor control of the face is the function of the nerve, while sensation from the face is determined by thenerve. a. Facial, trigeminal b. Trochlear, facial c. Facial, glossopharyngeal d. Trigeminal, glossopharyngeal e. Trigeminal, facial nerve 5. Tic douloureux is a painful neuralgia associated with the a. abducens b. olfactory c. trigeminal d. vagus e. facial 6. Which of the following nerves is responsible for movements of the tongue? a. CN V b. CN VII c. CN IX d. CN X e. CN XII 7. All of the following are branches of the trigeminal nerve EXCEPT a. ophthalmic b. maxillary c. mandibular d. greater petrosal 8. The facial and glossopharyngeal nervesExplanation / Answer
1. e) Turn their head toward the right, obviously to check who's there.
2. c) Trigeminal nerve.
3. d) Trigeminal nerve.
4. a) Facial, trigeminal.
5. c) Trigeminal. Tic douloureux/ trigeminal neuralgia is a disorder in which an intense pain is experienced in the face areas between the jaw and forehead because the trigeminal nerve is affected. The trigeminal nerve is mainly involved in sensing touch, pain, temperature, and pressure developed in the face.
6. e) CN XII i.e. hypoglossal nerve.
7. d) Greater petrosal.
8. a) Innervate the salivary gland. The three main salivary glands are parotid, submandibular and sublingual. They are innervated by sympathetic and parasympathetic branches of the autonomic nervous system. Cranial nerve glossopharyngeal (CN IX) is responsible for parasympathetic innervation of parotid gland while facial nerve (CN VII) play a role in receiving parasympathetic input for the submandibular and sublingual glands.
9. d) Glossopharyngeal nerve (IX). Mixed nerves have both motor and sensory functions. Other mixed cranial nerves are oculomotor, trigeminal, facial and vagus.
10. c) Vestibulocochlear nerve (VIII).
11. c) inability to taste.
12. c) Accessory nerve, cranial nerve XII because this nerve innervates the sternocleidomastoid muscles and any damage in this nerve will ultimately result in dysfunctional sternocleidomastoid muscles.
13. c) White column (matter).
14. d) corticospinal tract.
