Flashcards in Lecture 11 - Posterior Abdominal wall and retroperitoneal viscera Deck (29):
1

As we move laterally from the vertebral coloum there are _ musclces, what are they?

4 muscles:



pair of psoas major muscle
Psoas minor (missing in 1/3 of people)
Quadratus lumborum
Iliacus below

2

Where does iliacus originate?

iliac fossa - its tendon converges with psoas to insert into the lesser trochanter

3

Psoas majors origin is from the lower border of..

T12 - -vertebral bodies and medial side of the transverse process

4

The tendon of psoas passes ____ the inguinal ligament and attaches to..

The tendon of psoas passes beneath the inguinal ligament, attaches to the lesser trochanter

5

Psoas major is slender (disappearing - not in 1/3 of people) - the tendon blends with the ...

perisoteum of the pelvis

6

Quadratus Lumboum (QL) has to fill what space?

gap inferior to the 12th rib, superior to the poster half of the iliac crest and edge to edge with psoas major - stabilises the 12th rib

7

Where are the vessels, lumbar plexus, sympathetic trunk and ureter in relation to psoas major?

vessels 0 behind
lumbar plexus - within
sympathetic trunk and ureter - in front

8

Each of iliacus and Psoas is enclosed in ..

their own fascial sheath

- Psoas Fascia and iliacus fascia

9

QL and erector spinae are enclosed by..

thoracolumbar fascia

10

The thoracolumbar fascia has _ layers to it

Where do each of the layers come from?

3

Posterior - from the tip of spinous process

middle - from the tip of transverse process

anterior - from the front of the transverse process

11

The 3 layers of thoracolumbar fascia fuse along the line of the ___ rib

How many compartments does this create and what is in each one?

12th

2 compartments

anterior - contains QL

posterior - contains ES

12

What constitutes a psoas abscess?

bursting into psoas by contained in the fascial envelope

13

Which muscle do the kidney lie on?

QL

14

Which vertebrae are the Kidneys adjacent to?

T12/L3 - but related to diaphragm also, so will move with it


Surgeons can got in from behind - take out 12th rib

15

The right kidney sits a bit lower because of the ___

liver

16

The kidney have their own fibrous capsule called..

the renal capsule - also surrounded by a lot of fat

17

What is the organisation of the Kidney?

Outer cortex - continuous

inner medulla - discontinous (darker), divided into discrete pyramids with their apex pointing to the collecting system

18

Once the hilum enters the Kidney they are embedded in fat know as the ...

renal sinus

19

From anterior to posterior, the Kidney hilum:

renal vein,
renal artery (branches of aorta)
renal pelvis

(also nerves and lymphatics)

20

Just proximal to the kidney the renal artery divides into ...

5 Segmental arteries

21

The Right renal artery goes ____ the IVC to get to kidney

The left vein goes _____ of the aorta

The Right renal artery goes behind the IVC to get to kidney

The left vein goes in front of the aorta

22

What do the vessels migrate up?

Because of the differential growth rate relative to the posterior wall

23

Minor ____ form at the bottom of the medullar pyramids, then 2 or 3 of them form the major _____

Minor calyces form at the bottom of the medullar pyramids, then 2 or 3 of them form the major calyses

24

How many major calyses form the renal pelvis?

3

25

How long are the ureters in male?

25-30cm

26

Where do the ureters travel?

vertical descent on the posterior wall (on psoas major)

Tracks the tip of the lumbar transverse processes over the plevis

27

Where are the narrowings of the ureters path?

1. Where the renal pelvis narrows into the ureter

2. Where the ureter transverses over the pelvis

3. Where it enters the bladder

28

true or false

The adrenal glands are asymmetrical

True

29

What are the shapes of each adrenal gland?

Right - pyramidal

Left - more crescent

both very vacular
