Fig. 14. — The parotid region, after removal of the parotid gland, 

 veins that drain the masseter aud pterygoid muscles, and opens into the 

 internal maxillary at the upper border of the sterno-cephalic tendon. 



(3) V. auricularis posterior (magna), a vessel of considerable size, 

 drains the greater part of the external ear and follows the posterior 

 auricular artery during the initial part of its course. Later the vein 

 leaves the artery to join the internal maxillary at a variable point.
