The pelvic cavity contains the organs of reproduction, urinary bladder, pelvic colon, rectum, and numerous muscles.
What is the primary artery supplying the pelvic cavity?
The internal iliac artery is the major artery of the pelvis.
At which vertebral level does the common iliac artery bifurcate?
The bifurcation of the common iliac artery occurs at the vertebral level L5-S1.
What are the two trunks of the internal iliac artery?
The internal iliac artery divides into the anterior and posterior trunks.
What does the anterior trunk of the internal iliac artery supply?
The anterior trunk supplies the pelvic organs, perineum, gluteal region, and adductor region of the lower limb.
What is the function of the obturator artery?
The obturator artery supplies the muscles of the thigh’s adductor region and passes through the obturator canal.
What does the umbilical artery give rise to?
The umbilical artery gives rise to the superior vesical artery, which supplies the superior aspect of the urinary bladder.
What was the original function of the umbilical artery in utero?

What does the inferior vesical artery supply in males?

What does the vaginal artery supply in females?
The vaginal artery supplies the vagina and additional branches to the inferior bladder and rectum.
What is the course of the uterine artery in females?
The uterine artery travels within the cardinal ligament to the cervix and ascends along the lateral aspect of the uterus.
How does the uterine artery relate to the ovarian artery?
The uterine artery anastomoses with the ovarian artery at the origin of the fallopian tubes.
What structures are supplied by the middle rectal artery?
The middle rectal artery supplies the distal rectum and anastomoses with the superior and inferior rectal arteries.
What is the role of the internal pudendal artery?
The internal pudendal artery supplies the perineum and is accompanied by the pudendal nerve.
What region does the inferior gluteal artery supply?
The inferior gluteal artery supplies the gluteal region and hip joint.
What does the posterior trunk of the internal iliac artery supply?
The posterior trunk supplies the lower posterior abdominal wall, posterior pelvic wall, and gluteal region.
What does the iliolumbar artery supply?
The iliolumbar artery supplies the psoas major, quadratus lumborum, and the posterior abdominal wall.
What is the function of the lateral sacral arteries?
The lateral sacral arteries supply structures in the sacral canal, and the skin and muscle posterior to the sacrum.
What is the primary function of the superior gluteal artery?
The superior gluteal artery supplies the gluteal region, including the muscles and skin.
What is the origin of the ovarian artery?
The ovarian artery originates from the abdominal aorta, distal to the renal arteries.
What structures does the ovarian artery supply?
The ovarian artery supplies the ovaries and fallopian tubes in females.
Does the testicular artery enter the pelvis?
No, the testicular artery reaches the scrotum via the inguinal canal and does not enter the pelvis.
What is the function of the median sacral artery?
The median sacral artery supplies the sacrum, coccyx, and surrounding regions.
What is the origin of the superior rectal artery?
The superior rectal artery is the terminal continuation of the inferior mesenteric artery.
