DISTRIBUTION OF THE VEINS.

continues its course down the neck with the latter. It now 

 receives the auricular veins, anterior and posterior, and also 

 internal. The next is the temporal, the third is the internal 

 maxillary ; the latter in its course receives the blood of many 

 small veins, — the palato-maxillary, infra and supra orbitar, 

 ocular, inferior maxillary, and "deep temporal ; the fourth 

 branch, received by the jugular vein, is the parotideal, and 

 the last branches from the masseter muscles. 



THE OCCIPITAL VEIN 



Descends from the head, along with the occipital artery. 

 It brings blood from the occipital sinuses, receives veins from 

 the posterior lobes of the cerebrum and cerebellum ; also from 

 the dura mater. 



The submaxillary vein, a large branch of the jugular. It 

 is formed upon the side of the face by the concurrence of the 

 facial, labial, and varicose veins. It joins the trunk by the 

 side of the trachea, just below the parotid gland. In its 

 course it receives a number of veins ; the principal are — the 

 submental, sublingual, lingual, pharyngeal, and superior laryn- 

 geal veins. The facial vein results from an expansion of 

 small veins upon the side of the face, one of which is the 

 varicose from the masseter.* The labial vein is formed by the 

 union of a plexus of venous branches, coming principally 

 from the angle of the mouth, joined by others both from the 

 upper and lower lips. The varicose vein is buried in the 

 masseter. 



The jugular trunk having received the submaxillary, pro- 

 ceeds down the neck, and terminates in the anterior vena 

 cava, within the space between the two first ribs. Near the 

 junction of the submaxillary the jugular receives the small 

 thyroideal, cutaneous, muscular, and tracheal veins. Near its 

 termination it receives a branch of the superficial brachial, 

 and plate or plat vein. 



The vertebral vein runs the same course as the artery, 

 through the foramina, in the transverse processes of the cer- 

 vical vertebrae, with the exception of the last. This vein has
