Median artery

from Wikipedia, the free encyclopedia

The median artery ("central artery") is an artery of the forearm in mammals . In humans, this blood vessel is only rarely developed as a standard variant ; in contrast, in dogs , cats , pigs , horses and ruminants, it is the strongest vessel in the forearm and the direct continuation of the brachial artery after the common interosseous artery emerges .

The median artery accompanies the median nerve on the inside of the forearm and runs with it through the carpal tunnel . It discharges the radial artery in the upper third of the forearm . On the lower third of the pastern, it divides into the superficial palmar arteries ( Arteriae digitales palmares communes ) and is thus the main inflow to the forefoot. In the case of horses, it also sends a tributary to the Arcus palmaris profundus .

A study in southern Africa found that the incidence of a developed median artery in adults increased there from around 10% in the early 20th century to around 30% in the late 20th century. According to this study, the median artery is found above average in patients with painful carpal tunnel syndrome .
