Common Iliac Lymph Nodes
The common iliac lymph nodes, four to six in number, are grouped behind and on the sides of the common iliac artery, one or two being placed below the bifurcation of the aorta, in front of the fifth lumbar vertebra. They drain chiefly the hypogastric and external iliac glands, and their efferents pass to the lateral aortic glands The periaortic lymph nodes (also known as lumbar) are a group of lymph nodes that lie in front of the lumbar vertebrae near the aorta. These lymph nodes receive drainage from the gastrointestinal tract and the abdominal organs. The periaortic ly .... References Lymphatics of the torso {{Portal bar, Anatomy ...

Internal Iliac Lymph Nodes
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. The internal iliac lymph nodes also drain the superior half of the rectum, above the pectinate line. It does not receive lymph from the ovary or testis, which drain to the paraaortic lymph nodes.

External Iliac Lymph Nodes
The external iliac lymph nodes are lymph nodes, from eight to ten in number, that lie along the external iliac vessels. They are arranged in three groups, one on the lateral, another on the medial, and a third on the anterior aspect of the vessels; the third group is, however, sometimes absent. Their principal afferents are derived from the inguinal lymph nodes, the deep lymphatics of the abdominal wall below the umbilicus and of the adductor region of the thigh, and the lymphatics from the glans penis, glans clitoridis, the membranous urethra, the prostate, the fundus of the urinary bladder, the cervix uteri, and upper part of the vagina.

Lateral Aortic Lymph Nodes
The periaortic lymph nodes (also known as lumbar) are a group of lymph nodes that lie in front of the lumbar vertebrae near the aorta. These lymph nodes receive drainage from the gastrointestinal tract and the abdominal organs. The periaortic lymph nodes are different from the paraaortic lymph nodes. The periaortic group is the general group, that is subdivided into: preaortic, paraaortic, and retroaortic groups. The paraaortic group is synonymous with the lateral aortic group. Divisions The periaortic lymph node group is divided into three subgroups: preaortic, paraaortic, and retroaortic: * The preaortic group drains the gastrointestinal viscera. They can be subdivided into three groups: the celiac nodes, the superior mesenteric nodes, and the inferior mesenteric nodes. *The paraaortic group (also known as lateral aortic group) drains the iliac nodes, the ovaries, the testes and other pelvic organs. The lateral group nodes are located adjacent to the aorta, anterior to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Iliac Artery
The common iliac artery is a large artery of the abdomen paired on each side. It originates from the aortic bifurcation at the level of the 4th lumbar vertebra. It ends in front of the sacroiliac joint, one on either side, and each bifurcates into the external and internal iliac arteries. Structure The common iliac artery are about 4 cm long in adults and more than a centimeter in diameter. It begins as a branch of the aorta. This is at the level of the 4th lumbar vertebra. It runs inferolaterally, along the medial border of the psoas muscles. It bifurcates into the external iliac artery and the internal iliac artery at the pelvic brim, in front of the sacroiliac joints. The common iliac artery, and all of its branches, exist as paired structures (that is to say, there is one on the left side and one on the right). The distribution of the common iliac artery is basically the pelvis and lower limb (as the femoral artery) on the corresponding side. Relations Both common il ...

Lumbar Vertebra
The lumbar vertebrae are, in human anatomy, the five vertebrae between the rib cage and the pelvis. They are the largest segments of the vertebral column and are characterized by the absence of the foramen transversarium within the transverse process (since it is only found in the cervical region) and by the absence of facets on the sides of the body (as found only in the thoracic region). They are designated L1 to L5, starting at the top. The lumbar vertebrae help support the weight of the body, and permit movement. Human anatomy General characteristics The adjacent figure depicts the general characteristics of the first through fourth lumbar vertebrae. The fifth vertebra contains certain peculiarities, which are detailed below. As with other vertebrae, each lumbar vertebra consists of a ''vertebral body'' and a ''vertebral arch''. The vertebral arch, consisting of a pair of ''pedicles'' and a pair of ''laminae'', encloses the ''vertebral foramen'' (opening) and sup ...
