su·pe·ri·or tar·sal mus·cle

[TA]
a well-defined layer of smooth muscle that extends from the aponeurosis of the musculus levator palpebrae superioris to the superior tarsus; it is innervated by sympathetic nerves and acts to hold the upper lid in an elevated position; its paralysis in Horner syndrome result in ptosis.

superior tarsal muscle

a collection of smooth muscle fibers in companion with the levator palpebrae superioris passing from the inferior surface of the lavatory to the upper edge of the superior tarsus. Loss of function of either the levator palpebrae superioris or the superior tarsal muscle results in a ptosis of the upper eyelid.
