Document Summary
Strong, tough, and tense artery walls for withstanding pressure demands. Contain elastic fibers in order to stretch with systole and recoil with diastole. Contain muscle fibers (vascular smooth muscle) that control the amount of blood delivered to the tissues. Dilates and contracts, changing diameter of arteries to control blood flow. Brachial artery: biceps-triceps furrow of the upper arm and surfaces at the antecubital fossa in the elbow medial to the biceps tendon. Ulnar and radial arteries: run distally and form two arches supplying the hand (superficial and deep palmar arches) Radial: medial to the radius at the wrist. Ulnar: same relation to the ulna but deeper and often difficult to palpate: arteries in the leg: Femoral artery: under the inguinal ligament and down the thigh. Known as the popliteal artery when it courses posteriorly at the lower thigh. Anterior tibial artery --> dorsum of foot --> dorsalis pedis artery. Posterior tibial artery --> medial malleolus --> plantar arteries.
