The radial artery is positioned relative to which two muscles?

• A. Medial to the biceps and lateral to the triceps
• B. Medial to the brachioradialis and lateral to the flexor carpi radialis muscle
• C. Lateral to the brachialis and medial to the pronator teres
• D. Medial to the flexor carpi ulnaris and lateral to the flexor digitorum

Answer: (B)

The radial artery is correctly identified as being positioned medial to the brachioradialis and lateral to the flexor carpi radialis muscle. This anatomical positioning reflects the radial artery's route along the forearm, where it runs in the region of the wrist and hand. The brachioradialis is a muscle located on the lateral side of the forearm, making the radial artery's position medial to it. Conversely, the flexor carpi radialis, which is a muscle that flexes the wrist and also assists with its abduction, lies just lateral to the radial artery, emphasizing the artery's path along the radial side of the forearm. This anatomical relationship is significant for understanding vascular structures and their relevance in medical procedures or anatomical studies.
