| tibial arteries | The anterior and posterior arteries created at the bifurcation of the popliteal artery. The anterior tibial artery begins at the lower border of the popliteus muscle and lies along the tibia at the distal part of the leg to surface superficially anterior to the ankle joint. Its branches are distributed throughout the leg, ankle, and foot. The posterior tibial artery begins at the lower border of the popliteus muscle, lies behind the tibia in the lower part of its course, and is found situated between the medial malleolus and the medial process of the calcaneal tuberosity. Its branches are distributed throughout the leg and foot. (12 Dec 1998) |
| elastic layers of arteries | elastic laminae of arteries |
| epigastric arteries | Inferior and external epigastric arteries arise from external iliac; superficial from femoral; superior from internal thoracic. They supply the abdominal muscles, diaphragm, iliac region, and groin. The inferior epigastric artery is used in coronary artery bypass grafting and myocardial revascularization. (12 Dec 1998) |
