1

This splits into the common iliac artery

abdominal aorta

2

This splits into the external and internal iliac arteries

common iliac artery

3

This exits the pelvis as the femoral artery

external iliac artery

4

This enters the true pelvic and branches into posterior and anterior branches

internal iliac artery

5

What does the internal iliac artery and its branches supply

6

Iliolumbar

7

This posterior artery branch of internal iliac enters the ventral sacral foramina

lateral sacral

8

This artery supplies medial ilium and L5

iliolumbar

9

This artery supplies sacrum and ventral sacral nerves

lateral sacral

10

This posterior artery branch of internal iliac between L5 and S1 enters gluteal region superior to the piriformis muscle

superior gluteal

11

This posterior artery branch of internal iliac between S1/S2 or S2/S3 enters gluteal region inferior to piriformis muscle

inferior gluteal

12

This artery supplies gluteal muscles (medius and minimus) along with the accompanying nerve

superior gluteal

13

This artery supplies the gluteal muscle (maximus) along with the accompanying nerve

inferior gluteal

14

What is the path of the internal pudendal artery (posterior branch of internal iliac)

exits the pelvis through the greater sciatic foramen
enters the gluteal region inferomedial to piriformis
crosses over sacrpspinous ligament
re-enters the pelvis through the lesser sciatic foramen
*runs with the pudendal nerve

15

This artery supplies the urogenital and anal triangles

internal pudendal artery

16

This contains the internal pudendal artery and pudendal nerve back in pelvis

pudendal canal

17

This is formed by fascia of obturator interns mucles and runs anteriorly along ischiopubic ramus (toward the UG∆)

pudendal canal

18

This anterior artery branch of internal iliac runs toward the anterior abdominal wall

umbilical

19

This anterior artery branch of internal iliac runs through the obturator canal

obturator

20

This artery sends 3-4 superior vesicle arteries to bladder and terminates as medial umbilical ligament

umbilical

21

This artery supplies medial thigh running with the nerve

obturator

22

The obturator artery anastomoses with which vessels

inferior epigastric

23

What is meant by the Corona Mortis "crown of death"

since obturator anastomoses with inferior epigastric, damage to them could open the entire internal and external iliac system, causing death in minutes

24

This anterior artery branch of internal iliac anastomoses with ovarian artery from aorta

uterine

25

This artery supplies uterus, cervix, and superior vaginal canal

uterine

26

What are the male counterparts to the uterine artery in females

inferior vesical and artery of ductus deferens

27

This anterior artery branch of internal iliac supplies the inferior vaginal canal and posterior inferior bladder

vaginal

28

This anterior artery branch of internal iliac supplies the rectum

middle rectal

29

The ureter runs between which to arteries in females

uterine
vaginal

30

What kind of complications can arise from the ureter running between the uterine and vaginal arteries

During a hysterectomy, the ureter can be cut accidentally causing backup into the kidneys; kidney stones

31

This is the major vein of venous drainage of the pelvis and it ultimately runs to which vein

internal iliac
IVC

32

This venous system enters the IVC superiorly; hypertension; anastomoses

portal venous system

33

This is a venous network that surounds the bladder, prostate or uterus, and rectum

pelvic venous plexus

34

True or False
The pelvic venous plexuses intercommunicate prior to forming named vessels

True

35

What is the significance about the pelvic venous plexus intercommunication

there are clinical consequences involving the transportation of tumor cells or venous hypertension; it is valveless

36

What type of innervation is the sacral plexus

somatic innervation
S2-S4

37

What type of innervation is the autonomic plexuses

autonomic innervation

38

This forms the lumbosacral trunk and crosses over sacral ala

L4-L5

39

This emerges above the piriformis muscle

S1

40

These emerge through piriformis muscle

S2 and S3

41

These contribute to the pudendal nerve

S2-S4

42

These form the sciatic and gluteal nerve

L4-S3

43

Which levels of the spinal cord form the sacral plexus

L4-S4

44

What trunks form the sacral plexus

lumbosacral trunk
sympathetic trunk
sciatic trunk

45

The sympathetic fibers of the sacral plexus are made up of what spinal levels and nerves

T10-L2(3)
sacral splanchnic nerves

46

The parasympathetic fibers of the sacral plexus are made up of what spinal levels and nerves

S2-S4
pelvic splanchnic nerves

47

The superior hyopgastric plexus contains what type of fibers and forms what nerve(s) which go where

mostly sympathetic fibers
condenses to form 2 hyopgastric nerves
they diverge and curve outward bilateral to rectum

48

This plexus covers the bifurcation of aorta and upper sacrum

hypogastric plexus

49

The inferior hypogastric plexus contains what type of fibers and serves as what

both sympathetic and parasympathetic fibers
serves as main autonomic plexus of pelvis

50

This plexus covered pelvic viscera bilaterally

inferior hypogastric plexus

51

True or False
In the thorax, sympathetic chain ganglia are more medial

False; in the thorax that are more lateral and move medially as they descend

52

The pelvic sympathetic fibers are located where and terminate where

medial to sacral foramen
