Reason: Third cranial nerve, the oculomotor nerve is a motor nerve and carries impulses from the midbrain to these muscles for controlling the movements of the eyeball. This nerve arises from the floor of the midbrain.

Trochlear nerve (fourth cranial nerve) supplies nerve fibres to the superior oblique eye muscle. It is a motor nerve and helps in controlling the movement of the eyeball. This nerve originates from the floor of the midbrain.

Abducens nerve (sixth cranial nerve) originates from the pons varolii. It innervates the lateral rectus muscle of the eyeball. It is a motor nerve and controls the movements of the eyeball.
