If a person is having difficulty moving the eyeball towards the lateral side, which cranial nerve could be damaged? a) Hypoglossal nerve b) Abducens nerve c) Trigeminal nerve d) Trochlear nerve e) Optic nerve 22. From the list of cranial nerves: 1. Olfactory (0) 2.Optic () 3.Oculomotor (ill) 4. Trochlear (IV) 5. Vestibulocochlear (viI) Select the nerves that are sensory only: a)1,2,3 b) 2, 3, 4 c) 1, 2, 5 d) 2, 3, 5 e) 3, 4, 5

Explanation / Answer

18) B. Brachial plexus.

19) C. Occipital lobe. The primary visual cortex or striate cortex or V1 is located in the most posterior portion of the brain's occipital lobe

20) A. Hypoglossal nerve. Damage to the hypoglossal nerve cause difficulty with tongue movements, speech, chewing and swallowing, caused by dysfunction of cranial nerve nuclei.

21) E. Optic nerve.

22) C. Olfactory, optic and vestibulococchlear nerve are sensory cranial nerves. whereas oculomotor nerve and trochlear nerve are motor nerves.
