Which lymph node group is identified as the starting point in the described pelvic drainage sequence?

• A. Pelvic Lymph Nodes
• B. Popliteal Nodes
• C. Axillary Nodes
• D. Inguinal Nodes

Answer: (A)

Pelvic drainage begins with the pelvic lymph nodes because they are the first major collection points receiving lymph from pelvic organs such as the bladder, uterus/prostate, and rectum. From there, lymph moves onward to central nodes like the iliac groups and then toward the lumbar/para-aortic nodes as part of the typical pelvic drainage pathway. The other groups drain regions outside the pelvis—popliteal for the lower leg, axillary for the upper limb and chest wall, and inguinal for superficial lower abdomen, buttock, perineum, and parts of the lower limb—so they aren’t the starting point for pelvic drainage.
