GROSS ANATOMY

Detailed explanation-1: -The levator aponeurosis is a fascial tissue that connects the levator palpebrae superioris muscle (levator muscle) to the tarsus, a thick plate of connective tissue that lies in the upper eyelid, as well as to the overlying skin.

Detailed explanation-2: -The levator aponeurosis inserts via a fan of fibers. The first insertional attachment curves anteriorly around the orbital septum to form the lid crease. Approximately the anterior half of the aponeurosis inserts into pretarsal orbicularis and the overlying subcutaneous tissue.

Detailed explanation-3: -The function of the levator palpebrae superioris muscle is to raise the upper eyelid and to maintain the upper eyelid position.

Detailed explanation-4: -D – Behind the orbicularis oculi muscle is a layer of dense connective tissue called the tarsal plate. This gives the eyelid its shape and rigidity.
