Flashcards in Posterior Abdominal Wall (Text)* Deck (37):
1

Sensory innervation to the diaphragm is from what nerves?

- phrenic nerves (from central tendon)
- Intercostal nerves (from peripheral part of the diaphragm)

2

An aortic bifurcation usually occurs at highest point of the iliac crest. What vertebrae does this correspond to?

L4

3

Where do the gonadal arteries arise from?

Aorta

4

How does drainage pathway of the left and right gonadal veins differ?

- left gonadal vein drains into the left renal vein
- right gonadal vein drains directly into the IVC

5

What structure does the left gonadal vein drain into?

the left renal vein

6

What structure does the right gonadal vein drain into?

Directly into the IVC

7

Sympathetic innervation of the gut involves what two pathways?

- splanchnic
- suprarenal

8

What are the components of the Renal system (5)?

- kidneys
- suprarenal glands
- ureters
- urinary bladder
- urethra

9

How doe the positions of the kidneys differ between the right and left sides?

The right side sits lower than the left kidney because of its position to the liver

10

Perinephric fat (perirenal fat capsule)?

Surrounds the kidneys and their vessels as it extends into their hollow centers, the renal sinuses

11

Paranephric fat (pararenal fat body)?

- the extraperitoneal fat of the lumbar region that is most obvious posterior to the kidney.

- the renal fascia sends collagen fibers through this fat layer

12

The superior (apical) segment of the kidney is supplied by what artery?

- the superior (apical) segmental artery

13

The anterosuperior segment of the kidney is supplied by what artery?

- Anterosuperior segmental artery

14

The antero-inferior segment of the kindness is supplied by what artery?

- Antero-inferior segmental artery

15

The inferior segment of the kidney is supplied by what artery?

- inferior segmental artery

16

Which arteries of the kidneys originate from anterior branches of renal artery?

- superior (apical) segmental artery
- anterosuperosuperior segmental artery
- antero-inferior segmental artery
- inferior segmental artery

17

The posterior segment of the kidney is supplied by which artery?

- Posterior segmental artery

18

Which arteries of the kidneys arise from the posterior aspect of the renal artery?

- Posterior segmental artery

19

What are the 3 spots along the ureter where constriction can occur or stones can be caught?

- ureteropelvic junction
- crossing the external iliac artery and/or pelvic brim
- where the ureter traverses into the bladder wall

20

How far upward can the diaphragm extend?

As far as the 5th rib

21

Boundaries of the diaphragm?

- xiphisternal joint
- coastal margin
- body of TV12

22

These three peripheral origins (parts) insert on the central tendon of the diaphragm?

- stern all origin (part)
- costal origin (part)
- lumbar origin (part)

23

Which crura of the diaphragm is longer, the left or the right?

The right crus is longer

24

These three structures unite to form the aortic hiatus?

- medial arcuate ligament ligament
- right crus
- left crus

25

What do the posterior origins of the the diaphragm form on the posterior wall of the diaphragm?

- arcuate ligaments

26

The median arcuate ligament passes over what structure?

Aorta

27

The medial arcuate ligament passes over what structures?

- psoas major
- sympathetic trunks

28

The lateral arcuate ligament passes over what structures?

- quadratus lumborum
- subcostal nn, aa, vv.

29

The arcuate ligaments can also be called what?

Lumbocostal arches

- median lumbocostal arch
- medial lumbocostal arch
- lateral lumbocostal arches

30

What is the name of the potential site of hernias on the diaphragm called?

Vertebrocostal (lumbocostal) triangle

31

Aortic hiatus?

- T12
- aorta
- thoracic duct

32

Esophageal hiatus?

- T10
- esophagus
- esophageal branches of left gastric a.
- anterior and posterior vagal trunks
- lymphatics

33

Vena caval foramen?

- T8
- inferior vena cava
- terminal branches of R. Phrenic n.
- lymphatics from the liver

34

What passes through the sternocostal hiatus?

- superior epigastric vessels

35

Theses arteries supply the superior surface of the diaphragm (3)?

- pericardiacophrenic a
- musculophrenic a.
- superior phrenic a.

36

These vessels supply the inferior surface of the diaphragm?

Inferior phrenic aa. and vv.

- from celiac trunk or aorta, right passes posterior to IVC, left posterior to esophagus, posterior branches give off superior suprarenal aa.

37

What is the only motor nerve to the diaphragm?

Phrenic N. (C3-C5)
- branches run with the inferior phrenic artery.
