The levator palpebrae superioris (Latin for: elevating muscle of upper eyelid) is the muscle in the orbit that elevates the superior (upper) eyelid.
The levator palpebrae superioris muscle retracts the eyelid, exposing the cornea to the outside, giving vision.

Superior tarsal muscle

Müller's musclesuperior tarsalMueller muscle
The superior tarsal muscle, a smooth muscle, is attached to the levator palpebrae superioris, and inserts on the superior tarsal plate as well.
The superior tarsal muscle is a smooth muscle adjoining the levator palpebrae superioris muscle that helps to raise the upper eyelid.

Ptosis (eyelid)

ptosisblepharoptosisdrooping eyelid
Damage to this muscle or its innervation can cause ptosis, which is drooping of the eyelid.
Ptosis occurs due to dysfunction of the muscles that raise the eyelid or their nerve supply (oculomotor nerve for levator palpebrae superioris and sympathetic nerves for superior tarsal muscle).

Oculomotor nerve

oculomotorIIIcranial nerve III
As with most of the muscles of the orbit, the levator palpebrae receives somatic motor input from the ipsilateral superior division of the oculomotor nerve.
It supplies the superior rectus and levator palpebrae superioris.

Tarsus (eyelids)

This portion inserts on the skin of the upper eyelid, as well as the superior tarsal plate.
To the anterior surface of this plate the aponeurosis of the levator palpebræ superioris is attached.

The skin thus drawn upon is thrown into folds, especially radiating from the lateral angle of the eyelids; these folds become permanent in senescence, and form the so-called “crow's feet.” The Levator palpebræ superioris is the direct antagonist of this muscle; it raises the upper eyelid and exposes the front of the bulb of the eye.
