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.
