Internal iliac lymph nodes
Encyclopedia
The internal iliac lymph nodes (or hypogastric) surround the internal iliac artery
and its branches (the hypogastric vessels), and receive the lymphatics corresponding to the distribution of the branches of it, i. e., they receive lymphatics from all the pelvic viscera, from the deeper parts of the perineum
, including the membranous and cavernous portions of the urethra
, and from the buttock and back of the thigh
.
It does not receive lymph from the ovary
, testis, or superior half of the rectum
; the gonads drain to the paraaortic lymph nodes, while the superior half of the rectum drains to the pararectal lymph nodes

Internal iliac artery
The internal iliac artery is the main artery of the pelvis.-Structure:The internal iliac artery supplies the walls and viscera of the pelvis, the buttock, the reproductive organs, and the medial compartment of the thigh...

Ovary
The ovary is an ovum-producing reproductive organ, often found in pairs as part of the vertebrate female reproductive system. Ovaries in anatomically female individuals are analogous to testes in anatomically male individuals, in that they are both gonads and endocrine glands.-Human anatomy:Ovaries...

Rectum
The rectum is the final straight portion of the large intestine in some mammals, and the gut in others, terminating in the anus. The human rectum is about 12 cm long...

Pararectal lymph nodes
The pararectal lymph nodes are in contact with the muscular coat of the rectum. They drain the descending iliac and sigmoid parts of the colon and the upper part of the rectum; their efferents pass to the preaortic glands.-External links:...
