Cranial nerve and its function

Cranial Nerve and Major Functions:

I Olfactory :- smell

II Optic :- vision

III Oculomotor:- eyelid and eyeball movement

IV Trochlear :- innervates superior oblique turns eye downward and laterally

V Trigeminal chewing face & mouth touch & pain

VI Abducens turns eye laterally

VII Facial :- controls most facial expressions secretion of tears & saliva
taste

VIII Vestibulocochlear :- (auditory) hearing , equillibrium sensation

IX Glossopharyngeal :- taste , senses carotid blood pressure

X Vagus :- senses aortic blood pressure , slows heart rate ,stimulates digestive organs , taste

XI Spinal Accessory :- controls trapezius & sternocleidomastoid controls swallowing movements

XII Hypoglossal :- controls tongue

Which cranial nerve is the largest?
CN V (Trigeminal)

Which cranial nerve is the only one that exits the "posterior" side of the brainstem?
CN IV (Trochlear)

How many cranial nerves are responsible for eye movements?
Three: CN III (Oculomotor), IV (Trochlear), and VI (Abducens).

What does "abducens" refer to?
The abducens nerve carries motor impulses to the lateral rectus eye muscle which moves the eye laterally causing abduction of the eye.

Which cranial nerves carry gustatory (taste) information?
CN VII (Facial), CN IX (Glossopharyngeal) and CN X (Vagus).

Which cranial nerve is the longest?
CN X (Vagus) which reaches from the medulla to the digestive and urinary organs.

What two cranial nerves carry sensory information about blood pressure to the brain?
CN IX (Glossopharyngeal) and CN X (Vagus).

Which cranial nerve is responsible for pupillary constriction?
CN III (Oculomotor).
