Rete carpi dorsale

Arteries of the forearm and back of the hand.

The rete carpi dorsale (Latin for 'back of the hand network') is an arterial vascular network on the back of the wrist . In humans, it is fed by the ramus carpeus dorsalis of the arteria radialis and by the arteria interossea anterior and the ramus carpeus dorsalis of the arteria ulnaris . In humans, the arteriae metacarpales dorsales II to IV arise from the network of the back of the hand and run on the back of the metacarpal towards the fingers .

In quadrupedal mammals, the dorsal network of the hands is fed by the radial artery and the cranial interosseous artery . In addition, the arteria ulnaris of predators, the arteria interossea caudalis in predators and pigs and the arteria transversa cubiti in horses also send tributaries. From the network of the back of the hand, the number of deep metacarpal arteries ( Arteriae metacarpeae dorsales ) of different species arise . For predators there are four (I to IV), for pigs three (II to IV), for horses two (II and III) and for ruminants one (III).
