relations of the vein correspond pretty much with those of the 

 artery. 



Its tributaries are as follows : (i) the frontal vein ; (2) the 

 supra-orbital vein, which communicates with the ophthalmic 

 vein ; (3 the angular vein, which receives internally the lateral 

 nasal veins, and externally a few superior palpebral veins, whilst 

 posteriorly it communicates with the commencement of the superior 

 ophthalmic vein, and internally with its fellow of the opposite side 

 by means of the transverse nasal vein, which lies over the bridge of

the nose ; (4) a few inferior palpebral veins, which are in communi- 

 cation with the infra-orbital vein ; (5) the superior labial vein, 

 which issues from a plexus in the upper lip (the blood from the 

 similar plexus in the lower lip being chiefly conveyed by a few vessels 

 to the roof of the digastric triangle of the neck, where they take 

 part in the formation of the anterior jugular vein) ; (6) the deep 

 facial vein, of large size, which, emerging from the pterygoid plexus, 

 appears from behind the anterior border of the ramus of the inferior 

 maxilla and of the masseter muscle, and passes forwards over the 

 buccinator ; and (7) parotid, masseteric, and buccal branches.
