Detailed explanation-1: -The oculomotor nerve helps to adjust and coordinate eye position during movement. Several movements assist with this process: saccades, smooth pursuit, fixation, accommodation, vestibulo-ocular reflex, and optokinetic reflex. Saccades are rapid, jerky motions of the eye.

Detailed explanation-2: -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-3: -There are four basic types of eye movements: saccades, smooth pursuit movements, vergence movements, and vestibulo-ocular movements.

Detailed explanation-4: -Optic nerve: Ability to see. Oculomotor nerve: Ability to move and blink your eyes. Trochlear nerve: Ability to move your eyes up and down or back and forth.

Detailed explanation-5: -Each eye has six muscles attached to the sclera-the white part of the eye. These muscles, five of which are shown above, allow you to move the eye and track an object without turning your head. The eye muscles also allow you to shift your field of gaze left, right, up, down and diagonally.
