Where do the collectors of the medial upper arm territory drain?

• A. Supraclavicular
• B. Axillary
• C. Popliteal
• D. Parasternal

Answer: (B)

Upper limb lymph collectors channel lymph toward the axillary lymph nodes. The medial portion of the upper arm, though close to the chest, still drains into the same axillary pathways that receive lymph from the arm itself. From the axillary nodes, lymph proceeds to the subclavian trunk and onward into central drainage. Other regions have distinct drainage: parasternal nodes handle the medial chest wall and breast, supraclavicular nodes collect from the shoulder/neck area, and popliteal nodes collect from the leg. So the medial upper arm territory routes its collectors to the axillary nodes.
