THE VEINS OF THE HEAD AND NECK. 



communications in their course with the anterior branches of the temporal vein. It 

 descends vertically along the lower and inner part of the forehead, running parallel 

 with the corresponding vessel of the opposite side, and beneath the inner end of the 

 eyebrow it terminates in the angular vein. The right and left frontal veins commu- 

 nicate together by cross branches, and sometimes the two vessels are united for a 

 short distance in a common trunk, which divides again below. 



(b) The supraorlital vein, much smaller than the frontal, receives branches from 

 the lower part of the forehead, from the eyebrow, and from the upper eyelid, and 

 inclines inwards to join the termination of the frontal vein. It communicates 

 externally with the temporal, and posteriorly with the ophthalmic vein.

OF THE HEAD AND NECK.

1, frontal vein ; 2, supra- 

 orbital ; 3, angular vein, re- 

 ceiving superior palpebral and 

 nasal branches ; 4, 4, facial 

 vein on the face, receiving 

 inferior palpebral, superior 

 labial, parotid and masseteric 

 branches ; + indicates the 

 spot where it is joined by the 

 deep facial vein ; 5, facial 

 vein in the neck, being joined 

 by submental, with inferior 

 labial, glandular and inferior 

 palatine branches ; 6, common 

 facial vein, joining the in- 

 ternal jugular ; 7, communi- 

 cating branch to 8, the anterior 

 jugular ; 8', transverse branch 

 connecting the two anterior 

 jugular veins ; 9, superficial 

 temporal, and 10, middle tem- 

 poral, uniting to form the 

 common temporal vein, which 

 is receiving anterior auricular 

 and transverse facial branches; 

 10', orbital branch of middle 

 temporal ; 11 , internal maxil- 

 lary vein ; 12, tetnporo-maxil- 

 lary vein, the anterior division 

 of which unites with the facial, 

 while the posterior joins 13, 

 the posterior auricular vein, 

 to form 14, the external jugu- 

 lar ; 15, posterior external 

 jugular ; 16, transverse cer- 

 vical ; 17, suprascapular vein ; 

 18, occipital veins. 



(c) The angular vein, 

 formed by the junction 



of the supraorbital and frontal veins, is perceptible beneath the skin as it runs 

 obliquely downwards and outwards near the inner margin of the orbit, resting against 

 the side of the nose at its root. It receives on its outer side one or two small 

 superior palpelral veins from the upper eyelid, and anteriorly the nasal veins, which 

 pass upwards to join it from the side and dorsum of the nose ; behind, it communi- 

 cates freely with the commencement of the superior ophthalmic vein ; and 

 internally, it is united to its fellow by the transverse nasal vein, which forms an 

 arch over the bridge of the nose. On a level with the lower margin of the orbit it 

 becomes continuous with the facial vein.
