Between which tendons does the radial artery lie?

• A. Extensor pollicis longus and Extensor pollicis brevis
• B. Abductor pollicis longus and Extensor pollicis brevis
• C. Extensor digitorum and Flexor carpi radialis
• D. Abductor pollicis longus and Abductor pollicis brevis

Answer: (B)

The radial artery lies between the abductor pollicis longus and the extensor pollicis brevis tendons. This anatomical relationship is crucial for clinical procedures such as radial artery catheterization, where knowledge of surrounding structures is essential to avoid complications. The abductor pollicis longus is located more laterally, while the extensor pollicis brevis lies medially to the radial artery. Recognizing this positioning is significant when palpating for the radial pulse or conducting surgical interventions in that area. Understanding the anatomical landmarks aids in accurately identifying the artery and ensures safer clinical practices. The other options do not accurately describe the position of the radial artery as they involve tendons that are either not adjacent to the radial artery or are located in different anatomical regions, highlighting the importance of precise anatomical knowledge in surgical contexts.
