Brachial veins Brachial veins In human anatomy, the brachial veins are venae comitantes of the brachial artery in the arm proper. Because they are deep to muscle, they are considered deep veins. Their course is that of the brachial artery (in reverse): they begin where radial veins and ulnar veins join (corresponding to the bifurcation of the brachial artery). They end at the inferior border of the teres major muscle. At this point, the brachial veins join the basilic vein to form the axillary vein. The brachial veins also have small tributaries that drain the muscles of the upper arm, such as
Cystic artery fundus of the gallbladder before descending to supply the body and neck. When a single cystic artery arises from gastroduodenal artery it forms a configuration is known as "low-lying cystic artery", as it passes inferior to the cystic duct through the cholecystoduodenal ligament, and therefore remains outside the hepatobiliary triangle. This condition has alternatively been described as an inferior cystic artery and transposition of the cystic artery and duct with a prevalence at approximately 5%. In 25% of these patients with this course there will be a secondary arterial supply to the gallbladder, with the low-lying artery acting as the
