The arterial supply of the six metacarpophalangeal joints was studied in Bactrian camels. The arterial branches supplying the metacarpophalangeal joints were derived from the metacarpal distal perforating, medial and lateral branches of the palmar metacarpal artery III, medial and lateral branches of the palmar common digital artery III and the abaxial palmar proper digital arteries III and IV. These arterial branches were the proximal dorsoaxial distal metacarpal, distal dorsoaxial distal metacarpal, abaxial distal metacarpal, palmar distal metacarpal, interosseous distal metacarpal, dorsoaxial proximal proximal phalangeal, palmoaxial proximal proximal phalangeal, palmoabaxial proximal proximal phalangeal and dorsoabaxial proximal proximal phalangeal branches. They linked with each other around the metacarpophalangeal joint.
