The veins resemble in general those of the ox. Thus there is a
hemiazygos vein and two jugular veins, the internal one being relatively
larger than in the ox. A few differential features may be noted.
The =buccinator vein= resembles that of the horse, and unites with the
=vena reflexa= to form a short common trunk which joins the facial.
The =facial vein= resembles in general that of the horse. The =dorsal
nasal vein= is large, receives the veins from the snout, runs backward
in the groove of the nasal bone and joins the frontal vein; it is
connected with its fellow by a transverse branch, and anastomoses freely
with the malar and facial.
The veins of the distal parts of the limbs naturally present differences
which are correlated with those of the arteries.
