In the arms, locate pulsations in the arteries shown in Figure 1:

FIGURE 1. Arteries of the arm.

■ The brachial artery at the bend of the elbow just medial to the biceps tendon

■ The radial artery on the lateral flexor surface

■ The ulnar artery on the medial flexor surface, although overlying tissues may obscure pulsations in the ulnar artery

Two vascular arches within the hand interconnect the radial and ulnar arteries, doubly protecting circulation to the hand and fingers against possible arterial occlusion.
