Arteries to the Pelvis and Lower Limb

The abdominal aorta divides to form the common iliac arteries at the level of the pelvic brim. These vessels provide blood to the pelvic organs, gluteal region, and lower limbs.

Each common iliac artery descends a short distance and divides into an internal (hypogastric) branch and an external branch. The internal iliac artery gives off numerous branches to various pelvic muscles and visceral structures, as well as to the gluteal muscles and the

external genitalia. Figure 15.51 shows important branches of this vessel, including the following:

1. Iliolumbar artery to the ilium and muscles of the back.

2. Superior and inferior gluteal arteries to the gluteal muscles, pelvic muscles, and skin of the buttocks.

3. Internal pudendal artery to muscles in the distal portion of the alimentary canal, the external genitalia, and the hip joint.

4. Superior and inferior vesical arteries to the urinary bladder. In males, these vessels also supply the seminal vesicles and the prostate gland.

5. Middle rectal artery to the rectum.

6. Uterine artery to the uterus and vagina.

The external iliac artery provides the main blood supply to the lower limbs (fig. 15.52). It passes downward along the brim of the pelvis and gives off two large branches—an inferior epigastric artery and a deep circumflex iliac artery. These vessels supply the muscles and skin in the lower abdominal wall. Midway between the symphysis pubis and the anterior superior iliac spine of the ilium, the external iliac artery becomes the femoral artery.

The femoral artery, which passes fairly close to the anterior surface of the upper thigh, gives off many
