The main muscles, in the upper eyelid, that control the opening and closing are the orbicularis oculi and levator palpebrae superioris muscle.
2.
The "'levator palpebrae superioris "', which is innervated by a branch of the oculomotor nerve, also elevates the upper eyelid.
3.
Spencer was born without the muscle levator palpebrae superioris in his right upper eyelid, leading to permanent ptosis ( drooping of the upper eyelid ) and noticeable facial asymmetry.
4.
In this case, the ptosis is due to the result of interruption innervations to the sympathetic, autonomic Muller's muscle rather than the somatic levator palpebrae superioris muscle.
5.
This disease is most often in the facial muscles, levator palpebrae superioris, temporalis, sternocleidomastoids, distal muscles of the forearm, hand intrinsic muscles, and ankle dorsiflexors.
6.
It passes upward on the medial borders of the superior rectus muscle and levator palpebrae superioris, meeting the supraorbital nerve accompanies it between the roof of the orbit and levator palpebrae superioris to the supraorbital notch.
7.
It passes upward on the medial borders of the superior rectus muscle and levator palpebrae superioris, meeting the supraorbital nerve accompanies it between the roof of the orbit and levator palpebrae superioris to the supraorbital notch.
8.
The superior transverse ligament of the eye ( also known as Whitnall's ligament ) is a transverse ligament in the eye surrounding the levator palpebrae superioris muscle close to its partial implantation into the skin of the upper eyelid.
9.
If you let the levator palpebrae superioris muscle relax ( and if you're completely blind, there's little to remind you not to ), the eyelid falls down . talk ) 00 : 56, 28 May 2008 ( UTC)
10.
Failure of CN III will result in loss of function of the following muscles : medial rectus, superior rectus, inferior rectus, and inferior oblique as well as muscles that are responsible for opening the eyelid : levator palpebrae superioris muscle and the superior tarsal muscle ( Muller s muscle ).
