GENERAL HISTOLOGY

Detailed explanation-1: -Cranial nerve III works with other cranial nerves to control eye movements and support sensory functioning. Olfactory nerve (CN I) enables sense of smell. Optic nerve (CN II) enables vision.

Detailed explanation-2: -Neuroanatomy, Cranial Nerve 2 (Optic)

Detailed explanation-3: -Cranial nerves III (CNIII) (oculomotor), IV (trochlear), and VI (abducens) control the position of the eyeballs; CNIII influences the position of the eyelids and the size of the pupils.

Detailed explanation-4: -The optic nerve (CN II) contains sensory neurons dedicated to vision. The oculomotor nerve (CN III) provides motor function for all eye muscles except those supplied by cranial nerves IV and VI.

Detailed explanation-5: -optic nerve, second cranial nerve, which carries sensory nerve impulses from the more than one million ganglion cells of the retina toward the visual centres in the brain.
