Blood supply and Blood drainage of a developing limb bud Upper and lower limb buds

The limb buds are supplied by branches of the dorsal intersegmental arteries, which arise from the aorta and form a fine capillary network, throughout the mesenchyme. The premordial vascular pattern consists of, a primary axial artery and its branches, which rain into the aorta. The primary axial artery in the upper limb becomes the brachial artery in the arm and the common interosseous artery in the forearm, which has anterior and posterior interosseous branches The ulnar and radial arteries are terminal branches of the brachial artery As the digits form, the marginal sinus breaks down and the final venous pattern is represented by basilar and cephalic veins and their tributaries also develop. Blood in the marginal sinus drains into a peripheral vein In the thigh, the primary axial artery is represented by the deep artery of the thigh (Profunda femoris) In the leg, the primary axial artery is represented by the anterior and posterior tibial arteries #Bloodsupply #limbbud
