Flashcards in kidneys, ureter, bladder & post. abdominal wall Deck (20):

function and innervation of quadratus lumborum (most lateral)

-forced expiration & 12th rib support
-bend trunk to same side
- T12, L1-4


function, origin, insertion, and innervation of iliacus

- hip flexion
- origin = iliac fossa
- insertion = lesser tronchanter
- femoral nerve


innervation of psoas major

- L1-3


what supplies and drains the posterior abdominal wall

5x lumbar arteries and 5x lumbar veins


describe the surface anatomy of the kidneys

- sit on top of quadratus
- right kidney slightly lower than left due to liver
-left protected by rib 11 & 12
- right protected by rib 12
- ureter exists at L1


how are the kidneys protected

fatty tissue within renal fascia = perinephric fat
fatty tissue outside renal fascia = para-nephric fat


what is always the most posterior structure?

ureter/renal pelvis


describe the differences between the left and right blood supply

- renal arteries and veins (L1-2)
- right renal artery longer than left
- left renal vein 3x longer than right
- left renal vein goes posteriorly to SMA


describe the route of the ureters

1. exits kidneys at L1
2. extends down along surface of psoas
3. in line with transverse of lumbar spine
4. crosses bifurcation of common iliac artery
5. enters bladder on inferior surface of trigone


describe the arterial supply of the ureter

sup 1/3 = renal artery
mid 1/3 = gonal artery & iliac
inf 1/3 = superior vesical artey


referred pain of ureter

loin to groin


name the two areas where constriction of the ureter can occur

-junction of ureter and renal pelvis (PUJ)

-as they enter the wall of the bladder (UVJ / VUJ)


descsribe the cells of the bladder

- transitional epithelium
- rugae that can expand the size of the bladder
- muscular coat of SM = detruser muscle


describe the trigone

- triangular smooth area at the base of the bladder (no rugae)
- ureters enter & urethra exists
- between the two ureter openings is the inter-ureteric crest


describe the ANS to the bladder

SNS = sacral splanchnic nerves (L1-2)
PNS = pelvic splanchnic nerves


describe the 4 parts of the male urethra

- pre-prostatic
-prostatic (widest)
- membranous (thinnest)
- spongy


name the two branches off the L1 lumbar plexus

- iliohypogastric
(both motor and sensory)


Name the branch off L1 & L2 of the lumbar plexus

genitofemoral branch
(motor and sensory)


Name the branch off L2 & L3 of the lumbar plexus

lateral femoral cutaneous
(sensory only)


Name the branches off L2-4 of the lumbar plexus

femoral nerve & obturator nerve
(motor and sensory)
