VEINS. 



The FACIAL VEIN passes obliquely across the side of the face, extending from 

 the inner angle of the orbit, downwards and outwards, to the anterior margin of 

 the Masseter muscle. It lies to the outer side of the facial artery, and is not so 

 tortuous as that vessel. It commences in the frontal region, where it is called the 

 frontal vein; at the inner angle of the eye it has received the name of the angular 

 vein; and from this point to its termination, the facial vein.

The frontal vein commences on the anterior part of the skull, by a venous 

 plexus, which communicates with the anterior branches of the temporal vein ; the 

 veins converge to form a single trunk, which descends along the middle line of the 

 forehead parallel with the vein of the opposite side, and unites with it at the root 

 of the nose by a transverse trunk, called the nasal arch. Occasionally the frontal 

 veins join to form a single trunk which bifurcates at the root of the nose into the 

 two angular veins. At the nasal arch the branches diverge, and run along the side 

 of the root of the nose. The frontal vein, as it descends upon the forehead, 

 receives the supra-orbital vein ; the dorsal veins of the nose terminate ic the nasal
