Superior tarsal muscle The tarsi and their ligaments. Right eye; front view. (Muscle not labeled but region is visible.) Sagittal section of right orbital cavity. (Muscle not labeled but region is visible.) Latin musculus tarsalis superior Origin underside of levator palpebrae superioris Insertion superior tarsal plate of the eyelid Artery ophthalmic artery Nerve sympathetic nervous system Actions raise the upper eyelid
The superior tarsal muscle (also known as Müller's muscle) is a smooth muscle adjoining the levator palpebrae superioris muscle that helps to raise the upper eyelid.
The superior tarsal muscle originates on the underside of levator palpebrae superioris and inserts on the superior tarsal plate of the eyelid.
The superior tarsal muscle receives its innervation from the sympathetic nervous system on fibers carried along with the ophthalmic artery through the cavernous sinus. These postganglionic sympathetic fibers originate in the superior cervical ganglion.
The superior tarsal muscle works with the levator palpebrae superioris to raise the upper eyelid.
from Ancient Greek ταρσός, a "flat surface" typically used for drying.
The term "Müller's muscle" is sometimes used as a synonym.
