THE ORGANS OF DIGESTION 



a portion of the fascia, attached to the styloid process and the angle of the mandible, 

 is thickened to form the stylomandibular ligament which intervenes between the 

 parotid and submaxillary glands. 



The anterior surface of the gland is moulded on the posterior border of the rarnus 

 of the mandible with the attached Internal pterygoid and Masseter muscles, and 

 advances forward between the two Pterygoid muscles and overlaps the Masseter. 

 A part of the overlapping portion, immediately below the zygoma, is usually 

 detached, and is named the socia parotidis (gl. parotis accessoria). 



The outer or superficial surface, slightly tabulated, is covered by the integument, 

 the superficial fascia containing the facial branches of the great auricular nerve 

 and some small lymph nodes, and the fascia which forms the capsule of the gland.

The inner or deep surface extends inward by means of two processes, one of 

 which lies on the styloid process and the styloid group of muscles and projects 

 under the mastoid process and Sternomastoid muscle; the other is situated in 

 front of the styloid process and passes into the posterior part of the glenoid fossa 

 behind the temporomandibular joint. The deep surface is in contact with the 

 internal and external carotid arteries, the internal jugular vein and the vagus 

 and glossopharyngeal nerves. 



The anterior border lies on the superficial surface of the Masseter; the posterior 

 abuts on the external auditory meatus and the mastoid process, and overlaps 

 the anterior edge of the Sternomastoid. The superior border is in contact with the 

 zygomatic arch, and the inferior overlaps the posterior belly of the Digastric. 

 The inner border at the junction of the anterior and inner surfaces is in relation 

 with the styloid process and styloid muscles, and is separated from the pharyngeal 

 wall by some loose connective tissue. 



Structures within the Gland. The external carotid artery lies at first in contact 

 with the deep surface, and then in the substance of the gland. The artery gives
