It is also known as “Muller muscle”, a term that is also used to refer to a part of the ciliary muscle.
Superior tarsal Location
This well defined muscle starts from the bottom of levator palpebrae superioris and stretches from the galea aponeurotica to the superior tarsus. It has its point of insertion on the superior tarsal plate located in the eyelid.
Superior tarsal Function
The muscle helps keep the upper eyelid in an elevated position.
Superior tarsal Disorders
The actions of the muscle can be affected if some sections of the sympathetic nervous system suffer damage. This can lead to partial Ptosis, or drooping eyelid, as observed in Horner’s Syndrome.
