THE VEINS. g2t 
(2) A large communicating branch from the posterior facial. 
(3) The vena occipitalis, a large branch coming from the 
vertebral column (which it leaves by the atlantal foramen) and 
from the back of the head. 
d. V. facialis anterior (Fig. 131, c).—The anterior facial 
vein collects the blood from the face, the tongue, and adjacent 
parts; it joins the posterior facial (4) caudad of the angle of 
the jaw to form the external jugular vein. 
The anterior facial begins over the frontal bone caudad of 
the orbit, where it is known as the frontal vein (c’’). This 
runs along the dorsal border of the orbit, into which it dips. 
It sends a communicating branch into the orbit, and receives 
small veins (superior palpebral) from the upper eyelid. It 
then turns ventrad, passing along the cranial angle of the eye 
between the levator labii superioris proprius (5) and the orbicu- 
laris oculi (8) muscles, being called in this region the angular 
vein (c’). This receives branches (external nasal veins, £) 
from the side of the nose. The vein crosses the malar bone 
obliquely (now receiving the name anterior facial, c) and fol- 
lows the cranioventral border of the masseter muscle (9). As 
it passes the infraorbital foramen it receives through the 
foramen a small vein from within the orbit. It receives also 
the inferior palpebral (7) from the lower eyelid, and the 
superior labial vein (2) from the upper lip. Just caudad of the 
angle of the mouth it receives from beneath the cranioventral 
margin of the masseter the V. facialis profunda (/) described 
below. Still farther caudad it receives the inferior labial vein 
(gz) from the lower lip, and a small branch from the masseter 
muscle. Caudad of the middle of the cranioventral border of 
the masseter it receives from beneath the lymphatic gland of 
this region the large submental vein (/). Next the anterior 
facial vein receives a large communicating branch (V. trans- 
versa, 2) which passes transversely across the ventral surface 
of the throat and connects the two anterior facial veins of the 
opposite sides. From the middle of this communicating branch 
an unpaired trunk passes caudad in the middle line and divides 
into the two laryngeal veins, which pass to the larynx; a small 
branch is continued from the unpaired trunk craniad into the
