The oculomotor nerve, also known as cranial nerve III, arises from the midbrain, specifically from the ventral aspect near the interpeduncular fossa. It emerges between the cerebral peduncles and then travels through the lateral wall of the cavernous sinus to innervate several eye muscles and control pupil constriction.

Opening the eyes involves the cranial nerve called the oculomotor nerve (CN III). This nerve innervates the muscles responsible for raising the upper eyelid and controlling the pupil size.

number III. oculomotor
Yes it is motor and parasympathetic.
The parasympathetic fibers of the oculomotor nerve (cranial nerve III) control the contraction of the circular smooth muscle of the iris, causing pupil constriction.
Trochlear Nerve innervates Superior Oblique(extrinsic eye muscle)Oculomotor Nerve innervates Inferior Oblique, Superior Rectus, Inferior Rectus, and Medial Rectus (which are all extrinsic eye muscles) along with Ciliary Body, and the Iris (which are both intrinsic eye muscles)Abducens Nerve innervates Lateral Rectus(extrinsic eye muscle)
The cranial nerve involved in raising the eyelids is the oculomotor nerve (cranial nerve III). For focusing the lens of the eye for accommodation, the oculomotor nerve controls the ciliary muscle.
