The Orbicularis Oris. Remove the skin around the mouth ;md expose this 

 muscle. (Fig. 14.) This muscle has a rather strong fascia! attachment to the 

 alveolus of the superior maxilla. 



The zygomatici major and minor (Kig. 14) arise from the malar bone, and 

 are inserted into the outer part of the upper lip. 



The levator labii superioris alaeque nasi is inserted into the wing of the 

 nose and the upper lip. It arises from the nasal process of the superior maxilla, 

 on the margin of the orbit.

THE DEEPER LAYER or THE MUSCLES OF THE FACE AND NECK. 



The Orbicularis palpebrarum surrounds the base of the orbit. It consists 

 of two sets of fibres. One, called the palpebral, covers fat palptbrce or lids; the 

 other is external to this, and blends above with the occipto-frontalis muscle. It 

 has, internally, a firm, triple attadunoit to the internal angular process of the 

 frontal bone, and to the nasal process of the superior maxilla. Between these 

 two you will find a short, stout tendon that can be mistaken for nothing else 

 the ten do oculi or tcndo palpchrarnm. Figure IO shows its origin from the nasal 

 process of the superior maxilla in front of the lachrymal groove. Trace the 

 tendon toward the upper and lower lids and observe how it divides.
