On the extremities, territories are called __________.

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

Answer: (A)

In manual lymph drainage, the limb’s lymphatic drainage areas are organized as bundles. These are groups of lymphatic vessels that travel together and drain a specific skin territory, forming a functional unit. Treating by bundles mirrors how lymph flows along parallel channels toward the regional nodes, so stimulating each bundle helps move lymph from its whole territory toward nearby nodes (for the arm, toward axillary nodes; for the leg, toward inguinal nodes). Terms like regions, segments, or zones are more generic and don’t reflect this focused, bundle-based organization used in MLD practice.
