What branches supply the pinky side of the arm and the palms of the hand?

1. Radial arteries

2. Ulnas

3. Brachial arteries

4. Carpal arteries

The correct answer is: Ulnas

The pinky side of the arm and the palms of the hand are primarily supplied by the ulnar arteries. The ulnar artery runs along the inner side of the forearm and continues into the hand, where it supplies blood to the little finger and the corresponding side of the hand, including the palm. This arterial flow is essential for providing oxygen-rich blood to the muscles and tissues in these areas, facilitating normal function and health. The ulnar artery also plays a significant role in hand movements and sensations, particularly where the little finger is involved. In contrast, the radial arteries supply the thumb side of the arm and hand, the brachial arteries are the major arteries of the upper arm that bifurcate into the radial and ulnar arteries, and the carpal arteries serve the wrists rather than the specific areas mentioned in the question. Understanding the specific roles and locations of these arteries is vital for anyone preparing for a nail technician license, as it contributes to overall knowledge of anatomy and client safety during services.
