VEINS 



99 



Emissary veins : small veins passing through foramina in 

 the bones, and connecting the sinuses with the external veins 

 of the head. 



Facial: passes obliquely across side of face from inner 

 canthus to anterior border of masseter, being the continua- 

 tion of the angular vein from inner canthus of eye. Under 

 the inferior maxilla near the angle it unites with a branch 

 (communicating facial) from temporo-maxillary vein to form 

 a short trunk (the common facial), which, crossing sub- 

 maxillary gland, digastric and external carotid artery, empties 

 into the internal jugular vein. Also communicates with oph- 

 thalmic (vide cavernous sinus).

Temporal : from side and vertex of head, passes down over 

 zygoma, there receiving the middle temporal vein ; it then 

 courses down between condyle of jaw and external auditory 

 meatus into the substance of the parotid, where it joins the 

 internal maxillary vein to form the temporo-maxillary trunk.
