It first passes between the brachioradialis and the pronator teres, then descends between specific tendons, bypasses the radial styloid process and extends to the back of the hand and the palm, and participates in the formation of the palmar deep arch. It is worth noting that the lower segment of the radial artery is only covered by skin and fascia, which is an important part of clinical pulse palpation.
