Which artery divides into the radial and ulnar arteries?

The brachial artery is the correct answer because it is the major blood vessel that supplies the arm and is a continuation of the axillary artery. When it reaches the elbow region, the brachial artery typically bifurcates into two important branches: the radial artery and the ulnar artery. These two arteries supply blood to various structures in the forearm and hand. The radial artery runs along the radial side (thumb side) of the forearm, while the ulnar artery travels along the ulnar side (pinky side).

Understanding the anatomy and branching pattern of the brachial artery is crucial for vascular assessments and interventions in the upper extremities. This knowledge is particularly important for evaluating blood flow and diagnosing potential conditions such as radial or ulnar artery occlusion.

The other arteries mentioned have different anatomical roles and branching patterns. The subclavian artery primarily supplies blood to the upper limb, but it does not directly branch into the radial and ulnar arteries. The aorta, as the main artery of the body, branches off into several major arteries for systemic circulation but does not directly relate to the branches of the brachial artery. The femoral artery is located in the thigh and supplies blood to
