During examination, tenderness is reported on the most lateral structure in the cubital fossa. What is the correct order of structures from lateral to medial?

• A. Brachial artery, median nerve, biceps tendon
• B. Biceps tendon, medial nerve, brachial artery
• C. Biceps tendon, brachial artery, median nerve
• D. Median nerve, biceps tendon, brachial artery

Answer: (C)

In the cubital fossa, the arrangement of structures from lateral to medial is crucial for understanding clinical presentations and conducting examinations. The correct ordering is: biceps tendon, brachial artery, and median nerve.

The biceps tendon is the most lateral structure in the cubital fossa. It acts as a prominent landmark and can be palpated when the elbow is flexed. Following the biceps tendon, the brachial artery is located centrally within the fossa. It plays a significant role in supplying blood to the arm and forearm. Finally, the median nerve is situated medially in the cubital fossa and is responsible for innervating several muscles in the forearm and hand.

Understanding this anatomical arrangement is essential for clinicians when assessing elbow injuries, conducting manual therapies, and planning surgical interventions. Knowing which structures are located where helps to avoid potential nerve damage or vascular injury during procedures.
