Abstract
Two direct branches of the brachiocephalic artery are frequently present in the dog. These are described in 33 dogs and their incidence recorded. One supplies the lower cervical trachea and esophagus and the other the thymus gland and sometimes the pericardium. Suggested names are βTracheoesophagealβ and βThymopericardialβ branches of the brachiocephalic. The embryology of the blood vessels of the esophagus is discussed and the identification of the tracheoesophageal with a secondary anastomotic vessel is considered most likely. Occasional branches from the brachiocephalic artery in man are reviewed. The Arteria Thyroidea Ima seems to bear the closest relationship to this vessel described in the dog. The value of this study in relation to heartβlung preparations and to experimental surgery of the esophagus is suggested.

The conus artery has long been recognized as an important source of collateral blood supply to a significantly diseased left anterior descending artery. This artery which arises 50% of the time from a separate orifice in the right sinus of Valsalva may also provide collateral circulation to a diseas
## Abstract The arterial supply to the sciatic nerve was investigated in 20 human lower limbs (10 right, 10 left) from 20 cadavers (14 females, aged 84 Β± 9.6 years, range 66β95 years: 6 males, aged 80 Β± 8.2 years, range 70β90 years). In all limbs examined at least 1 sciatic artery could be identifi
The origin of transverse arterial branches that contribute to the arterial supply of the odontoid process (dens axis) is not clear. Dissections were performed on 20 injected fetal and adult human cranio-cervical junctions to demonstrate the origin of the arteries that contribute feeding branches to
