PLATE XXXIX. 

 ANTERIOR TRIANGLE, SUPERFICIAL VIEW. 



In this dissection, after the skin was removed, the platysma was cut across, and its 

 npper portion turned over the jaw. The cervical fascia and the superficial lymphatic 

 glands lying in the submaxillary triangle were removed and the space cleaned of fat. _ 



The following diagram has been introduced to show a plan of the superficial veins 

 of the neck : (a) Temporal ; (b) internal maxillary ; (c) posterior auricular ; (d) anterior 

 branch of temporo-maxillary going to join the facial; (e) external jugular formed 

 by the junction of the posterior auricular and posterior branch of the temporo- 



maxillary ; (/) posterior external jugular, which usually receives the mastoid vein from 

 the lateral sinus ; (g) placed between the transverse cervical and the supra-scapular 

 veins ; (h) facial ; (i) submental ; (k) anterior jugular ; (1) lingual ; (m) superior thyroid ; 

 (n) middle thyroid ; (p) internal jugular ; (p) subclavian ; (r) jugulo-cephalic ; (s) deep 

 facial which communicates with the pterygoid plexus, this plexus receives a vein through 

 the foramen Vesalii from the cavernous sinus ; (t) communication between the angular 

 vein and the ophthalmic (which flows into the cavernous sinus).
