The levator palpebrae superioris is a thin flat muscle with a triangular shape that is situated in the eyelid. This muscle raises the eyelid, the direct opposite of the orbicularis palpebrarum muscle. These two muscles are used to blink and during sleep. The
levator palpebrae superioris originates from the lesser wing of the sphenoid bone and inserts into the walls of the orbit. It is innervated by the third cranial nerve (oculomotor) and is supplied by branches of the ophthalmic artery. Research Levator Palpebrae Superioris
