A

the right renal artery

34
Q

where does each renal artery divide into 5 segmental arteries?

A

the Hilum

35
Q

do the segmental arteries of the renal artery use collateral circulation?

A

NO –> they are end arteries

36
Q

where do the renal veins empty into?

A

the inferior vena cava

37
Q

where are the renal veins found?

A

ANTERIOR to renal arteries

38
Q

which renal vein is longer?

A

left

39
Q

which renal vein passes anteriorly over the aorta?

A

the left renal vein

40
Q

why is the right renal artery longer?

A

it must pass posterior to the IVC

41
Q

why is the right renal vein shorter?

A

its found closer to the IVC

42
Q

what muscle do the ureters pass over to enter the bladder?

A

the Psoas major

43
Q

in what direction do the ureters run in relation to the gonadal vessels?

A

obliquely and posteriorly

44
Q

what condition increases the risk for kidney stones?

A

compression of the ureters –> causes a decrease in flow

45
Q

from what 3 sources do the ureter arteries arise?

A

1) renal artery- main source
2) testicular/ovarian artery
3) abdominal aorta

46
Q

where do the veins of ureters drain into?

A

similarly named veins

47
Q

what branch of the renal arteries supplies the ureters?

A

the ureteric branch

48
Q

what is lithotripsy? and what does it do?

A

ultrasonic crushing of large kidney stones. allows them to pass thru the ureter to the bladder

49
Q

where does the pain start when kidney stones are being passed?

A

from side and back between ribs- goes to pelvis and inguinal region

50
Q

what region of cutaneous innervation is associated with kidney stone pain?

A

T11-12

51
Q

which adrenal gland is roughly triangular?

A

the right gland

52
Q

where does the right adrenal gland lie?

A

superior to right kidney, POSTERIOR to inferior vena cava

53
Q

what shape does the left adrenal gland take?

A

semilunar

54
Q

where does the left adrenal gland lie?

A

superomedial to left kidney near the Hilum

55
Q

what are the 3 main parts of the adrenal glands?

A

1) fibrous capsule
2) adrenal cortex
3) adrenal medulla- acts as SYMPATHETIC ganglion

56
Q

which 3 arteries deliver blood to the adrenal glands?

A

1) suprarenal arteries (6-8 branches) from inf phrenic artery
2) middle suprarenal (from abdominal artery)
3) inferior suprarenal (from renal artery)

57
Q

name the muscles of the posterior abdominal wall

A

1) transverse abdominus
2) quadratus lumborum
3) psoas major
4) iliacus
5) psoas minor
6) diaphragm

58
Q

what arteries supply the posterior wall? how many branches do they have?

A

Lumbar arteries. come off of the abdominal aorta, give 4 pairs of arteries

59
Q

what do the nerves of the ventral rami of T12-L4 become? where are they located?

A

Form the lumbar plexus. Found beneath fascia of posterior abdominal muscles
