Internal iliac artery
The arteria iliaca interna ("inner pelvic artery") emerges in humans on each side of the body as the weaker of the two branches of the arteria iliaca commonis as an indirect continuation of the aorta . In domestic animals, it comes directly from the aorta. It supplies the organs of the pelvis , but also the body wall with blood .
The internal iliac artery initially continues in a caudal direction to the posterior upper edge of the muscular pelvic floor in order to transfer its branches to both the outside and the inside.
In humans it gives off the following branches to the bowels ( visceral branches ):
-
Umbilical artery (plays a major role in the fetal circulation and ispartially obliterated after birth - notochord arteriae umbilicalis )
- Arteria vesicalis superior (superior bladder artery)
- Arteria uterina (artery to the uterus )
- Inferior vesical artery (lower bladder artery)
- Arteria rectalis media (middle rectal artery ). The levator ani muscle , which separates the two arteries,can be usedas a guide to identify the arteriae rectales media et inferior .
- Arteria pudenda interna (artery for the external genitalia and the erectile tissue ), it gives off the arteria rectalis inferior (unpaired) to the anus muscles.
The following branches to the abdominal wall and musculoskeletal structures of the pelvis ( parietal branches ) also arise from the internal iliac artery :
- Iliolumbar artery
- Lateral sacral artery (branches to the sacrum )
- Obturator artery (branches to the adductors and dorsal hip muscles)
- Arteria glutaea superior (branches to the gluteal muscles)
- Inferior gluteal artery (branches to the gluteal muscles)
