The (facial vein) commences at the side of the root of the
Nose , and is a direct continuation of the
Angular Vein .
It lies behind the
External Maxillary (facial) Artery and follows a less tortuous course.
It runs obliquely downward and backward, beneath the
Zygomaticus and zygomatic head of the
Quadratus Labii Superioris , descends along the anterior border and then on the superficial surface of the
Masseter , crosses over the body of the mandible, and passes obliquely backward, beneath the
Platysma and
Cervical Fascia , superficial to the
Submaxillary Gland , the
Digastricus and
Stylohyoideus .
The facial vein has no
Valves , and its walls are not so flaccid as most
Superficial Veins .
