optic nerve
CN II visual informetion
oculomotor nerve
CN III: (motor) controls eye movement; raises eye lids
trochlear nerve

abducens nerve
Cranial nerve VI. abduction of eyeball lateral rotation
Glossopharyngeal

Name the cranial nerve(s) most involved in each of the following: moving your eyeball; sticking out your tongue; controlling your heart rate and digestive activity; shrugging your shoulders.
The oculomotor (III), trochlear (IV), and abducens (VI) nerves control eye movements. Sticking out your tongue involves the hypoglossal nerve (XII). The vagus nerve (X) influences heart rate and digestive activity. The accessory nerve (XI) innervates the trapezius muscle, which is involved in shoulder shrugging.
Name the 12 pairs of cranial nerves; indicate the body region and structures innervated by each.
Twelve pairs of cranial nerves are associated with the brain The first two pairs attach to the forebrain, and the rest are associated with the brain stem. 1. Olfactory 2. Optic 3. Oculomotor 4.
