Flashcards in Posterior Abdomen Deck (18):
1

Function of posterior abdominal wall

Supports organs
Facilitates respiration
Provides movement at the hip

2

Where does the retroperitoneal space lie?

In between posterior abdominal wall and peritoneum

3

Kidneys and Pancreas

retroperitoneal organs

4

What structures protect the kidneys

ribs
quadratus lumborum
Psoas major

5

Where do the adrenal veins drain to?

The renal veins

6

What vein off the IVC needs to travel longer to reach the kidney?

Left renal vein
Enters the renal hilum:
- renal vein
- renal artery
- ureter

7

The adrenal medulla is made up of...

Chromaffin cells
Preganglionic sympathetically go straight to the organ!

The adrenal medulla is like a giant post-ganglionic sympathetic

8

What drains into the left renal vein?

Left gonadal vein
Left gonadal artery comes off the aorta

- reminds us of the origin of testes on the posterior abd. Wall

9

Ureter exists in the...

Retroperitoneal space
- muscular ducts that convey urine from the Renal pelvis -> urinary bladder
- courses within retroperitoneal space

10

Where does ureter naturally constrict at?

- renal pelvis
- crossing the pelvic brim
- entering the bladder

Kidney stones might be lodged here causing FLANK PAIN (loin->groin)
T11-L2 : as the kidney stone moves, the pain moves

11

What innervates the ureter?

Sympathetic/parasympathetic
Aorticorenal Plexus

Sympa: regulates peristalsis
Parasympathetic: vagus/pelvic sphlanchnic nerve

12

Transplantation of kidney to the iliac fossa

The renal artery/vein is anastomosed to the common or external iliac fossa

Ureter is made as short as possible:
- must have a good supply, therefore you take the 1st third of the ureter with it

13

What cervical nerves innervate the diaphragm?

C3, C4, C5

14

What nerves go to the suprarenal glands?

Greater splanchnic nerve
Lesser splanchnic nerve
Least splanchnic nerve


15

What is the ganglia to the suprarenal glands?

celiac ganglia
Superior mesenteric ganglia
Aorticorenal ganglia

16

What sympathetic fibers go directly onto the cells of the adrenal medulla?

Preganglionic sympathetics

17

What sympathetic nerve fibers go to the blood vessels of kidney?

Postganglionic sympathetics

18

What are the two main nerves of the lumbar plexus?

Femoral nerve -> quadriceps
Obturator Nerve -> Adductor Muscles
