1

Abdominal aorta bifurcates where into what

L4
Right and left common iliac artery

2

Common iliac bifurcates where into what

Pelvic brim
Internal and external iliac

3

External iliac runs

Under inguinal ligament to become femoral artery

4

Internal iliac runs

Into the true pelvis and becomes posterior and anterior

5

Anterior branches of internal iliac artery

Umbilical artery
Obturator artery
Inferior gluteal
Internal pudendal
Visceral
All parietal but visceral

6

Posterior branches of internal iliac artery

Iliolumbar
Lateral sacral
Superior gluteal
All parietal

7

Umbilical artery

Becomes occluded in adult as medial umbilical ligament
May give rise to superior vesicle artery and uterine artery

8

Obturator artery runs and supplies

Leaves with obturator nerve and vein through obturator canal
Supplies iliacus muscle and other in lower limb

9

Inferior gluteal artery runs

Terminal branch
Passes through greater sciatic foramen

10

Internal pudendal artery supplies

Main artery of perineum

11

Superior vesicle artery supplies

Supplies superior part of bladder

12

Inferior vesicle artery supplies

Supplies inferior part of bladder, prostate, and seminal vesicles

13

Uterine artery runs, supplies

Cross ureter and passes with cardinal ligament (transverse cervical) to reach the uterus
Supplies uterus and anastomoses with overian artery

14

Vaginal artery supplies

Superior region of vagina

15

Middle rectal artery supplies

Supplies rectum
Anastomoses with superior and inferior rectal

16

Iliolumbar artery supplies

Iliacus and psoas muscles

17

Lateral sacral artery supplies

Spinal branches entering anterior sacral foramina

18

Superior gluteal artery runs

Between lumbosacral trunk and S1
Exits pelvis through greater foramen

19

Each pelvic organ in true pelvis surrounded by

Plexus of veins that drain into internal iliac vein to reach IVC

20

Exception to plexuses of true pelvis

Superior mesenteric vein follower superior rectal artery to hepatic portal vein

21

Pelvic venous plexus clinical consideration

Easy spread of disease from pelvis to vertebral column
Pevlic communicate with external and internal vertebral plexus

22

Sacral plexus exits through and innervates

L4-S4
Anterior sacral foramen
Pelvis, perineum, posterior thigh, most of lower leg, all of foot

23

Lumbosacral trunk and where it runs

L4/5 as they run over pelvic brim into true pelvis

24

Pudendal nerve arises from and innervates

Arises from S2-S4
Perineum

25

Coccygeal plexus innervates

Area around coccyx and anus

26

Where is aortic plexus renamed and to what

L4/5
Superior hypogastric plexus

27

Where is superior hypogastric plexus renamed and to what

True pelvis
Inferior hypogastric plexus (pelvic plexuses)

28

Below L2, there are only ______ communicans

Grey rami communcans

29

Sacral splanchnics

Preganglionic sympathetic fibers that join hypogastric plexus for distribution

30

Pevlic splanchnics and where they exit into true pevlis

Preganglionic parasympathetic fibers from S2-S4
Descend with cauda equina - anterior sacral foramen
Also join hypogastric plexi
