The obturator artery is a branch of the internal iliac artery that 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 an anterior branch and a posterior branch.
the obturator artery (from the anterior division of the internal iliac artery) with the inferior epigastric artery (from the external iliac artery) the obturator artery (from the anterior division of the internal iliac artery) with the medial circumflex femoral artery (from the profunda femoris artery) the middle rectal artery (from the ...
The obturator vein begins in the upper portion of the adductor region of the thigh and enters the pelvis through the upper part of the obturator foramen, in the obturator canal. It runs backward and upward on the lateral wall of the pelvis below the obturator artery , and then passes between the ureter and the internal iliac artery , to end in ...
Variations in origin and course of obturator artery. (Obturator canal not labeled, but visible at bottom center of each diagram.) The obturator canal is formed between the obturator membrane and the pelvis. [1] The obturator artery, obturator vein, and obturator nerve all travel through the canal.
A portion remains open as a branch of the anterior division of the internal iliac artery. The umbilical artery is found in the pelvis, and gives rise to the superior vesical arteries, which in males usually supplies the artery to the ductus deferens. Alternately, the latter artery can be supplied by the inferior vesical artery in some individuals.
The obturator foramen is situated inferior and somewhat anterior to the acetabulum.It is bounded by the pubis bone and the ischium: superiorly by the (grooved obturator surface) of the superior ramus of pubis, inferiorly by the ramus of ischium, and laterally by (the anterior edge of) the body of ischium (including by the margin of the acetabulum).
A new study found that having a history of COVID-19 can double a person’s long-term risk for heart attack, stroke, and even death. Stanley Hazen, MD, PhD, a cardiologist, said several surprising ...
The iliac branch of the iliolumbar artery (ramus iliacus) descends to supply the iliacus muscle; some offsets, running between the muscle and the bone, anastomose with the iliac branches of the obturator artery; one of these enters an oblique canal to supply the bone, while others run along the crest of the ilium, distributing branches to the gluteal and abdominal muscles, and anastomosing in ...
