Which term best describes lymph drainage territories on the extremities?

• A. Networks
• B. Bundles
• C. Zones
• D. Regions

Answer: (B)

Bundles describe the organized, parallel pathways of lymphatic vessels that run through the extremities and carry lymph toward proximal drainage points. Thinking in terms of bundles emphasizes that lymph moves along defined, grouped channels rather than a loose mesh or broad geographic area. In manual lymph drainage practice, you follow these bundled routes to guide lymph toward the nearest regional nodes, such as the axillary or inguinal nodes, which is why this term fits best for describing drainage territories in the limbs.

The other terms are less precise for this concept. Networks suggest a more scattered web of vessels rather than clearly defined parallel conduits. Zones or regions imply larger, generic areas rather than the specific, organized pathways of lymph flow.
