lab 9: Brain and Cranial Nerves

Vocabulary practice flashcards covering the functions, anatomical locations, and pathways of the twelve cranial nerves from Tables 18.2 and 18.3.

1.Olfactory Nerve (Cranial Nerve I) — Function

Receives sensory information from the nose.

2.Optic Nerve (Cranial Nerve II) — Function

Receives sensory information from the eye, transmitting the sense of vision to the brain.

3.Oculomotor Nerve (Cranial Nerve III) — Function

Transmits motor information to move the eye muscles, particularly to the medial, superior, and inferior rectus muscles and to the inferior oblique muscle.

4.Trochlear Nerve (Cranial Nerve IV) — Function

Transmits motor information to move the eye muscles, particularly the superior oblique muscle.

5. Trigeminal Nerve (Cranial Nerve V) — Function

A three-branched nerve; transmits both sensory information from and motor information to the head.

6. Abducens Nerve (Cranial Nerve VI) — Function

A motor nerve; moves the eye muscles, particularly the lateral rectus muscle.

7. Facial Nerve (Cranial Nerve VII) — Function

Receives sensory information from the anterior tongue and takes motor information to the head muscles.

8. Vestibulocochlear Nerve (Cranial Nerve VIII) — Function

Receives sensory information from the ear; the vestibular part transmits equilibrium information and the cochlear part transmits acoustic information.

9. Glossopharyngeal Nerve (Cranial Nerve IX) — Function

A mixed nerve of the tongue and throat; receives information on taste.

10. Vagus Nerve (Cranial Nerve X) — Function

Receives sensory information from abdomen, thorax, neck, and root of tongue; transmits motor information to pharynx and larynx; controls autonomic functions of heart, digestive organs, spleen, and kidneys.

11. Accessory Nerve (Cranial Nerve XI) — Function

A motor nerve to the muscles of the neck; moves the head.

12. Hypoglossal Nerve (Cranial Nerve XII) — Function

A motor nerve to the tongue.
