Levator palpebrae superioris muscle

Last revised by Assoc Prof Frank Gaillard on 18 Mar 2022

The levator palpebrae superioris muscle is a small muscle of the superior orbit that elevates and retracts the upper eyelid. It is not part of the extraocular muscles; it does not insert on the globe and therefore does not produce eye movements. But it is considered to be one of the facial muscles.

It is composed of skeletal striated muscle fibers but on its undersurface, smooth muscle fibers form the superior tarsal muscle (Müller muscle), which is under sympathetic control (and sometimes considered a separate muscle).
