Is obturator canal below femoral ring?
The obturator artery passes antero-inferiorly (forwards and downwards) on the lateral wall of the pelvis, to the upper part of the obturator foramen, and, escaping from the pelvic cavity through the obturator canal, it divides into both an anterior and a posterior branch. The obturator artery sometimes arises from the main stem or from the posterior trunk of the internal iliac artery, or it may arise from the superior gluteal artery; occasionally it arises from the external iliac. The obturator artery sometimes arises from the main stem or from the posterior trunk of the internal iliac artery, or it may arise from the superior gluteal artery; occasionally it arises from the external iliac. In about two out of every seven cases it arises from the inferior epigastric and descends almost vertically to the upper part of the obturator foramen. The artery in this course usually lies in contact with the external iliac vein, and on the lateral side of the femoral ring, in such cases it would n
