The venae esophageae are numerous smaller veins formed in 

 closely woven plexuses in the region of the esophagus along the 

 neck. Some pass upward and some downward. 



The venae tracheales are located on the supero-lateral side of the 

 trachea and along the edge of the lateral tracheal muscle. They 

 have numerous anastomoses transversely with the longitudinal 

 vein of the cervical region, anteriorly with the vena lingualis, and 

 on the left side with the left jugular vein. 



The vena subscapularis passes along the median line of the scapula 

 to the side of the jugular vein, and anastomoses with the vertebral 

 vein. 



The venae glandularum thyroidearum are several small, short 

 veins coming from the thyroid gland. 



The vena vertebralis, originating near the atlas, is a continuation 

 of the internal occipita 1 vein. The internal occipital vein receives 

 the bulk of the blood from the brain and communicates with the 

 lateral veins of the cervical region and collects blood from the cer- 

 vical vertebra. The vertebral vein accompanies the vertebral 

 artery and the deep sympathetic nerve trunk in the vertebral canal. 

 The vein either leaves this canal with the vertebral artery at a point 

 near the last two vertebral nerve trunks of the brachial plexus, or 

 it leaves the canal one vertebra in front of the vertebral artery. 



THE VEINS OF THE DORSAL REGION 



The vena vertebralis lateralis dorsalis collects blood from the 

 cervical vertebrae, from the dorsal vertebrae, and from the inter- 

 costal region.
