 No vena transversa exists. 



The temporo-ma.xillary vein (T-M.'V) is formed within the 

 parotid gland by the union of the internal maxillary (I.M.V) 

 and superficial temporal (S.T.Y) veins. It drains the side of 

 the head and pterygoid region and parotid gland. It receives 

 the very short internal jugular vein (I.J.V), passes under the 



Text-fieure 42. 



The cephalic veins (A) and thoracic thymus gland (B). L.I.V: superior inter- 

 costal vein ascending from behind the heart to enter the innominate vein ; 

 P.B.D : posterior belly of the digastric muscle ; T.G : thymus gland (the 

 siuall veins and arteries on its surface are the thymic vessels, described in
