Direct branches from common iliac:
|
External iliac
Internal iliac (ant and post trunk) |
|
|
Direct branches from abdominal aorta
|
Testicular arteries
Ovarian arteries |
|
|
Bifurcations occur at:
|
L4 - Of aorta
L5 - of common iliac S1 - Internal iliac bifurcates into anterior and posterior division |
|
|
Branches of posterior trunk of internal iliac artery:
|
Iliolumbar artery
Lateral sacral artery Superior gluteal artery |
|
|
Branches of anterior trunk of internal iliac artery
|
1. Umbilial artery
2. Inferior vesical artery 3. Middle rectal artery 4. Uterine artery (F) 5. Vaginal artery (F) 6. Obturator artery 7. Internal pudendal artery 8. Inferior gluteal artery |
|
|
Umbilical artery, branches and characteristics
|
Only proximal part is patent after birth. Branch: Superior vesical artery.
|
|
|
Inferior vesical artery supplies:
|
Vesical fundus
Prostate Seminal vesicles Ureter (ampulla of ductus deferens) |
|
|
Middle rectal artery - characteristics and supply
|
Usually arises with the inferior vesical artery. Supplies:
lower rectum seminal vesicles prostate |
|
|
The 3 segments of the course of the uterine artery
|
1. Descending - on lateral wall
2. Transverse - runs on levator ani to cervix. Goes in broad ligament and CROSSES URETER. 3. Ascending - laterally to uterus, goes up in broad ligament. |
|
|
The uterine artery supplies
|
1. Cervix
2. Vagina, anastomosing with bb of the vaginal arteries to form 2 median longitudinal vessels, the azygos arteries of the vagina (the anterior and posterior azygos a). 3. Body of uterus. 4. Uterine tube. 5. Round ligament. |
|
|
Branches of uterine artery
|
Round ligament branch
Tubal branch Ovarian branch |
|
|
Vaginal artery has branches to the:
|
Vestibular bulb
Vesical fundus Adjacent part of rectum |
|
|
Vagina is supplied by:
|
Superior part: Uterine artery
Middle part: Vaginal artery Inferior part: Branches of pudendal artery |
|
|
Relations of obturator artery
|
Leaves pelvic cavity by obturator canal, divides into ant and post branches.
It is crossed by the ureter and ductus deferens, SEPARATING IT from the parietal peritoneum!! Sometimes the obturator artery and the umbilical artery cross each other. |
|
|
Pelvic branches of obturator artery
|
Iliac bb to iliac fossa, supplying bone and iliacus
Vesical branch passing medially to the bladder Pubic branch which ascends over pubis |
|
|
Branches of obturator artery outside of the pelvis
|
Anterior branch supplies obturator internus
Posterior branch supplies muscles attached to the ischial tuberosity. |
|
|
Internal pudendal artery in the male
|
Exits pelvic cavity through greater sciatic foramen. Curves around sacrospinous ligament to enter perineum through lesser sciatic foramen. Traverses pudendal canal in lateral wall of ischiorectal fossa. Goes along the medial margin of inf pubic ramus. Ends behind inf pubic ligament, dividing into the deep and dorsal arteries of penis.
|
|
|
Branches of internal pudendal artery in male
|
- Muscular bb
- Interior rectal artery - escapes from pudendal canal and divides into 2-3 bb crossing ischiorectal fossa. - Perineal artery - approaces scrotum in superficial perineal region - artery of bulb of penis - Urethral artery - reaches glans penis - Deep artery of penis - Dorsal artery of penis |
|
|
Internal pudendal artery in the female - branches
|
Posterior labial branches
Artery of the bulb Deep artery of clitoris Dorsal artery of clitoris |
|
|
Course of inferior gluteal artery
|
Descends anterior to sacral plexus and piriformis, posterior to internal pudendal artery. Goes through lower part of greater sciatic foramen to reach gluteal region.
|
|
|
Inferior gluteal artery supplies:
|
Vesical fundus, seminal vescicles, prostate, piriformis, levator ani, coccygeus
|
|
|
Lateral visceral branches of the abdominal aorta:
|
Suprarenal artery
Renal artery Testicular or ovarian artery |
