All of the collectors in the forearm converge and bottleneck at the _________________.

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

Answer: (B)

Collectors from the forearm drain toward the elbow region and funnel into the epitrochlear (cubital) lymph nodes located in the antecubital fossa. This area acts as the bottleneck where multiple forearm lymphatic channels converge before the fluid moves on to the axillary regional nodes. The antecubital fossa is therefore the key convergence point for forearm lymphatics. The other options don’t serve this drainage role: the carpal tunnel is at the wrist and involves nerves; the brachial plexus is a network of nerves in the shoulder/axilla; and while the cubital fossa is the same general elbow region, the question specifically highlights the antecubital fossa as the convergence site for forearm lymphatics.
