Question

which cranial nerve carries the visual impulses from the retina to the brain?
trochlear nerve
oculomotor nerve
optic nerve
ophthalmic division of trigeminal nerve

Explanation:

The optic nerve (cranial nerve II) is responsible for transmitting visual impulses from the retina to the brain. The trochlear nerve (cranial nerve IV) controls eye movement. The oculomotor nerve (cranial nerve III) also controls eye movement and other functions like pupil constriction. The ophthalmic division of the trigeminal nerve (cranial nerve V) is involved in sensory functions (e.g., pain, touch) from the eye area, not visual impulse transmission.

Answer:

Optic nerve
