 that region. Its collateral branches are : 1 — Pharyn- 

 geal, terminating in the velum palati and the walls of 

 the pharynx; 2 — Lingual, goes to the tongue in its 

 upper portion, anastomosing in front with that of the

 supplies lower part of the tongue and the buccal mu-

 lower lip and muscles of the inferior part of the lat- 

 eral surface of the face ; 5 — Superior coronary, goes 

 to the upper lip, where it anastomoses with the 

 palate. 



2. Maxillo-muscular. — Passes between the parotid 

 gland and the posterior labial border of the maxillary 

 bone, where it divides into an external superficial and 

 an internal deep, branches going to the masseter 

 muscles. 



3. Posterior auricular. — Passes upwards under the 

 parotid to the base of the concha, passing on its pos- 

 terior face to the superior extremity, sending off a few 

 glandular and muscular branches. , 



Superficial temporal — Pas^'''*trp^rds' between 

 the parotid, guttural pouch and the condyle of the max-
