Study Notes
Internal Iliac Artery
- Branches into anterior and posterior divisions at the upper part of the greater sciatic foramen
- Anterior division (parietal branches):
- Inferior gluteal artery
- Internal pudendal artery
- Obturator artery
- Anterior division (visceral branches):
- Umbilical artery
- Middle rectal artery
- Inferior vesical artery (or vaginal artery in females)
- Uterine artery (in females)
Internal Iliac Vein
- Formed by the union of veins that accompany the branches of the internal iliac arteries
- Receives veins corresponding to the branches of the internal iliac arteries, except for:
- Iliolumbar vein (parietal), which ends in the common iliac vein
- Umbilical artery, which does not have a corresponding vein
Sacral Plexus
- Located in front of the piriformis muscle
- Formed by the lumbosacral trunk (L4,5) and sacral nerves (S1-3)
- Branches:
- Superior gluteal nerve (L4,5, S1)
- Inferior gluteal nerve (L5, S1,2)
- Nerve to quadratus femoris
- Nerve to obturator internus
- Sciatic nerve (S2,3)
- Pudendal nerve (S2,3,4)
- Perforating cutaneous nerve
- Coccygeal plexus (S4,5 and coccygeal nerves)
Coccygeal Plexus
- Located on the coccygeus muscle
- Formed by the lower part of S4, S5, and coccygeal nerves
- Branches:
- Anococcygeal nerves to coccygeus and levator ani
Pelvic Arrangement and Peritoneum
- In males:
- Rectum: upper 1/3 covered by peritoneum on front and sides, middle 1/3 covered on front, lower 1/3 uncovered
- Peritoneum forms the recto-vesical pouch
- Peritoneum passes from urinary bladder to line the anterior abdominal wall
- In females:
- Rectum: upper 1/3 covered by peritoneum on front and sides, middle 1/3 covered on front, lower 1/3 uncovered
- Peritoneum forms the recto-vaginal or Douglas pouch
- Peritoneum covers the uterus (except the ant surface of cervix) and forms the utero-vesical pouch
- Peritoneum passes from urinary bladder to line the anterior abdominal wall
