0

Posterior abdominal wall is composed of what

Five lumbar vertebrae
Diaphragm
Thoracolumbar fascia
Lumbar plexus
Posterior abdominal muscles
- psoas
- quadratus lumborum
- iliacus
- transverse abdominal
- lateral oblique muscles

1

The para vertebral gutters are where

Either side of the lumbar vertebral column

2

The deepest part of the para vertebral gutters is occupied by what

The kidneys

3

What lies in the anteriorly protruding vertebral column

The abdominal aorta

4

In lean individuals where is the abdominal aorta

Close to the anterior abdominal wall

5

What covers the posterior abdominal wall

A continuous layer of endoabdominal fascia

6

The psoas facia covers what

Psoas major

7

What is very long and foes all the way to the femur

The psoas fascia

8

What is thick and strong in the lumbar region and thin and transparent in the region where it covers the thoracic parts of the deep muscle

Thoracic bar fascia

9

the anterior layer of the thoracolumbar fascia covers what

Quadratus lumborum

10

When the following of these are diseased what happens what follows

Pancreas
Lumbar lymph nodes
Ureters
Cecum
Sigmoid colon

Movement of the iliopsoas is painful

11

Iliopsoas test

Having someone lie on their side and push their leg against the resistance of a hand, if pain occurs intra- abdominal inflammation may be present

Inflamed appendix- right psoas pain

12

What may cause spasm of the iliopsoas as a protective reflex

Disease of the intervertebral and sacral joints

13

Tb of vertebral column is what

Very common

14

Hematogenous spread

Infection spreading through the blood to the vertebrae

15

An abscess form TB in the lumbar region can do what

Spread from the vertebrae into the psoas sheath where it can make a psoas abscess

16

Pus from a psoas access usually surfaces where

In the thigh

17

What is another way that pus can reach the psoas sheath

By passing from the posterior part of the manubrium when the thoracic vertebrae is diseased

18

The posterior abdominal wall has what kind of nervous system

Autonomic and somatic

19

Partial lumbar sympathectomy

When the surgeon splits the muscles of the anterior abdominal wall and moves the peritoneum medically and exposes the edge of the psoas major

20

The relationship of the sympathetic trunk to the aorta and Ivc can make these large vessels do what

Be vulnerable to injury during lumbar sympathectomy

21

The lumbar plexus nerve network is composed of what

Anterior rami l1-l4

22

Femoral nerve

L2-l4 comes from the lateral border of the psoas major

23

Obturator nerve

L2-l4 from the medial border of the psoas major and goes to the lesser pelvis

24

What passes over the ala(wing) of the sacrum and descends to the pelvis to form the sacral plexus with anterior rami s1-s4

Lumbosacral trunk

25

What nerves run superior and parallel to the Iliad crest and pierce the transverse abdominal near the anterior superior iliac spin (Asia)

Ilioinguinal
Iliohypogastric

26

What nerve perches the psoas major and runs inferiority on its anterior surface

Genitofemoral nerve

27

Which nerve runs along the iliacus and enters the thigh deep to the inguinal ligament

Lateral femoral cutaneous nerve

28

What nerve is only present 10% of the time

Accessory Obturator nerve

29

Length of abdominal aorta

13cm

30

Abdominal aorta begins where

At the abdominal hiatus in the diaphragm (t12) and ends at the level of L4 because it divides into right and left

31

Just before leaving the abdomen the external iliac artery gives rise to what

Deep circumflex a. And inferior epigastric a.

32

Since the aorta lies posterior to the pancreas and sto,ach what in these organs could cause pulsation of the aorta

A tumor

33

Deep palpating of the mid abdomen can detect what

Aneurysm

34

What is associated with acute rupture of an abdominal aortic aneurysium?

Severe pain in the abdomen or back

35

Acute ruptures aneurysm of the aorta have what percent of fatality if not detected

90% because of heavy blood loss

36

In small children or thin people you can press on the inferior part of the abdomen to do what

Stop bleeding in the lower limbs or pelvis

37

The site of aortic bifurcation is indicated where

Just left of the midpoint of the line joining the highest points of the lilac crest

38

There are how many collateral routes for blood to return to the heart if the Ivc is blocked

3

- inferior epigastric vein
- superior epigastric vein
- thoracoepigastric vein

39

What is fairly common and can occur inferior to the renal veins

Left Ivc

During development these veins should have disappeared

40

Where are the lymphatic vessels in the posterior abdominal wall

On aorta, Ivc, and iliac vessels

41

Where do the common iliac lymph receive lymph from

External and interns
Iliac lymph nodes

42

Whree does the inferior end of the thoracic duct lie

Anterior to the bodies of l1-l2

43

What part of the thoracic duct varies greatly in size

The chyle cisterns

44

All the lymph from the lower part of the body converges and goes to where

Thoracic duct

45

What does the thoracic duct ascend thorough

The aortic hiatus in the diaphragm

46

The thoracic duct ends when it enters where

At the junction of left subclavian vein and internal jugular vein
