The forearm lymph collection bottlenecks at the Antecubital Fossa.

• A. Cubital Fossa
• B. Antecubital Fossa
• C. Carpal Tunnel
• D. Brachial Artery

Answer: (B)

Lymph flow from the forearm concentrates and passes through a single pathway as it reaches the elbow region, located in the antecubital fossa. This area houses the elbow (epitrochlear) lymph nodes and serves as the main junction where forearm lymphatics converge before moving on to the upper-arm nodes. Because multiple channels funnel into this compact region, it acts as a bottleneck for forearm lymph collection. The term antecubital fossa refers to this elbow crease area and is the precise location described, making it the best choice. The cubital fossa is the same anatomical region, so using antecubital fossa is just the more specific term in this context. The carpal tunnel and the brachial artery are unrelated to forearm lymph drainage—one is a nerve tunnel at the wrist, the other a major blood vessel in the arm.
