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 tongue. The communicating branch receives also near its junction with the anterior facial a rather large superficial branch (_e_) which comes from the sides of the lower jaw and passes across the lymphatic gland (12) to join the communicating branch. [Illustration: FIG. 131.--SUPERFICIAL VEINS AND ARTERIES OF THE FACE. _a_, external jugular vein; _b_, posterior facial vein; _c_, anterior facial vein (_c′_, angular vein; _c″_, frontal vein); _d_, communicating branch with opposite anterior facial; _e_, superficial branch from lower jaw; _f_, submental vein; _g_, inferior labial vein; _h_, deep facial vein; _i_, superior labial vein; _j_, inferior palpebral vein; _k_, external nasal veins; _l_, posterior auricular vein; _m_, superficial temporal vein; _n_, anterior auricular vein; _o_, external maxillary artery; _p_, inferior labial artery; _q_, superior labial artery; _r_, infraorbital arteries; _s_, superficial temporal artery; _u_, anterior auricular branch of posterior auricular artery. 1, M. adductor auris superior; 2, M. corrugator supercilii medialis; 3, M. corrugator supercilii lateralis; 4, M. levator labii superioris alæque nasi; 5, M. levator labii superioris proprius; 6, M. myrtiformis; 7, M. orbicularis oris; 8, M. orbicularis oculi; 9, M. masseter; 10, parotid gland; 11, submaxillary gland; 12, lymphatic glands.] The following larger branches of the anterior facial are not described above: =V. facialis profunda= (Fig. 131, _h_).--The deep facial vein enters the anterior facial from beneath the masseter, just caudad of the angle of the mouth. It collects branches from the soft and hard palates and the teeth, these branches passing along with the corresponding arteries for a distance, then uniting and passing ventrolaterad beneath the zygomatic arch to join the anterior facial. The deep facial vein also receives branches which come from the venous plexus that lies in the same region as the arterial carotid plexus.
