Dissection of right orbit from a superior approach
Insertion of levator palpebrae superioris muscle, anterosuperior view
The aponeurosis of insertion of the levator palpebrae superioris muscle (6) has been exposed. The superior part of the lacrimal gland has been cut away and the fascia removed from the aponeurosis. The upper eyelid (13) has been dissected to display the extension of this aponeurosis onto the anterior surface of the tarsus (12) as well as its attachment to the skin anterior to the tarsus (14). This insertion is also visible in reel 52-3. The insertion of the lateral "horn" of the aponeurosis into the orbital tubercle of the zygoma is visible at 11. The medial "horn" of the aponeurosis (23) extends downward toward the medial wall of the orbit. Variation in thickness of the bone of the lateral wall of the orbit is well shown in this view.
