the eye, accompanies its artery across the face and the angle 

 of the jaw, and then joins the anterior division of the temporo- 

 maxillary, to form the common facial. [876] 



The external jugular begins, behind the angle of the lower 

 jaw, by the union of the posterior auricular and posterior di- 

 vision of the temporo-maxillary. It descends over the Sterno- 

 mastoid and third part of the subclavian artery to join the 

 subclavian vein. Its tributaries are: posterior external jugular , 

 draining the posterior triangle; transverse cervical; supra- 

 scapular; anterior jugular, draining the anterior triangle, de- 

 scending from the chin over the Sterno-mastoid, and com- 

 municating with the common facial and the opposite anterior 

 jugular by anastomotic branches. [877] 



The internal maxillary begins in a plexus (pterygoid) which 

 lies in the pterygoid and zygomatic fossae and has branches 

 corresponding to those of the artery. It accompanies the first 

 part of the artery and joins the superficial temporal in the 

 parotid gland, forming the temporo-maxillary. The latter de- 

 scends over the external carotid to the lower part of the parot- 

 id gland and there divides into two divisions, viz. : posterior, 

 joining the posterior auricular to form the external jugular; 

 and anterior, joining the facial to form the common facial.

LYMPHATICS. 



Glands. Those of the head are the following: occipital, ly- 

 ing over the insertion of the Trapezius ; mastoid, lying over the 

 mastoid bone and insertion of the Sterno-mastoid; internal 

 maxillary, lying on the Buccinator and pharyngeal wall along 

 the internal maxillary artery; parotid, lying both superficially 

 and deeply in the gland. [909] 



The facial glands are the following: mandibular, lying along 

 the facial artery as it crosses the mandible ; buccal, lying on 

 the fascia covering the front part of the Buccinator; lingual, 

 lying between the Genio-hyo-glossi and on the outer sur-
