Origin

edit

The submental artery is the largest branch of the facial artery in the neck.[1]

It arises from the facial artery just as the facial artery splits the submandibular gland.[1]

Course and distribution

edit

The artery passes anterior-ward upon the mylohyoid muscle, coursing inferior to the body of the mandible and deep to the digastric muscle.[citation needed] Here, the artery supplies adjacent muscles and skin; it also forms anastomoses with the sublingual artery and with the mylohyoid branch of the inferior alveolar artery. Upon reaching the chin, artery turns superior-ward[1] at the mandibular symphysis[citation needed] to pass over the mandible before dividing into a superficial branch and a deep branch; the two terminal branches are distributed to the chin and lower lip, and form anastomoses with the inferior labial and mental arteries.[1]
