26
Q

what level is the coeliac trunk? what does it supply?

A

T12

the foregut - from the mouth to the proximal duodenum

27
Q

what level is the superior mesenteric artery? what does it supply?

A

L1

midgut - distal duodenum to the proximal 2/3rds of transverse colon.

28
Q

What level is the renal arteries?

A

L1-L2

29
Q

What level is the inferior mesenteric artery? what does it supply?

A

L3

hindgut - distal 1/3rd of transverse colon - rectum.

30
Q

which level is the spleen?

A

T9-T11.

31
Q

what is the renal corpuscle?

A

The filtering part of the kidney (the glomerulus and the bowman capsule).

32
Q

What is the functional unit of the kidney?

A

the nephron - made from the renal corpuscle + proximal convoluted tubule + loop of henle + distal convoluted tubule + collecting duct.

33
Q

What is the outer part of the kidney called? what structures are in there?

A

The cortex - the glomerulus, proximal and distal tubules and the beginning and end of the loop of henle.

34
Q

What are the triangles in the middle of the kidney called?What do they have inside them?

A

the medullary pyramids - the loop of henle along with the collecting ducts.

35
Q

what is the drainage flow of the urine?

A

filtrate enters the collecting ducts - these drain down to the apex of the pyramid (into minor calyces) - 2/3/4 of these minor calyces drain into a major calyx - 2 or 3 of these major calyces drains into the renal pelvis - which eventually becomes the ureter.

36
Q

what type of epithelium is in the tubes of the kidneys?

A

Transitional epithelium - all the way from the minor calyx to the urethra after the bladder. theres also connective tissue and smooth muscle.

37
Q

Histology: what are the 3 cells in the glomerulus?

A

podocytes
capillary cells
mesangial cells

38
Q

what structures are found in the cortex?

A

glomeruli, proximal and distal tubules

39
Q

histology: how can you tell between distal and proximal tubules?

A

proximal tubules are full, distal tubules have an empty lumen

40
Q

what structures are found in the medulla?

A

the loop of henle, collecting ducts, part of the cortex - renal columns.

41
Q

which side is the IVC and abdominal aorta on?

A

IVC is on the right side, abdominal aorta is on the left side.

42
Q

What is posterior and anterior - renal arteries or veins?

A

renal arteries run posterior to the renal veins.

43
Q

is the right or left renal vein longer?

A

right is shorter, left is longer.

44
Q

is the right or left renal artery longer?

A

right is longer, left is shorter.

45
Q

what vein drains into the left renal vein?

A

left gonadal vein

46
Q

What is the muscle called in the bladder?

A

the detrusor muscle

47
Q

which muscle of the back does the ureters run anteriorly too?

A

the psoas major muscle

48
Q

which bifurcation does the ureters run over?

A

runs over the common iliac artery - just as it splits into the external and internal iliac artery.

49
Q

in males - what crosses anteriorly to the ureters?

A

the vas deferens

50
Q

in females - what crosses anteriorly to the ureters?

A

the uterine arteries

51
Q

where in the bladder does the ureters open into?

A

the vesicoureteric opening, posterior and lateral of the bladder wall.

52
Q

where are the three ureteric constriction sites?

A

the ureteropelvic junction (or ureteric orifice), crossing the common iliac artery and entering the bladder (the vesicoureteric junction).

53
Q

which part of the bladder does the urethra exit?

A

the urethral crest

54
Q

which type of tissue makes up the bladder wall?

A

transitional epithelium

55
Q

what is transitional epithelium?

A

this is stratified epithelium which is round in shape when its not distended.

56
Q

which bony joint is directly anterior to the bladder?

A

the pubic symphyses.

57
Q

what is transitional epithelium also called in the ureters and bladder?

A

urothelium

58
Q

what is the benefit of having transitional epithelium

A

it can stretch lots

59
Q

on an x-ray, where do you see the ureters?

A

running in line with the transverse processes

60
Q

what does the transitional epithelium look like when its NOT distended?

A

cuboid/columnar cells

61
Q

what does the transitional epithelium look like when it IS distended?

A

squamous cells (stretched)

62
Q

what is the ureter derived from embryologically?

A

ureteric buds - from the mesonephric duct.

63
Q

what is special about the trigone muscle?

A

the epithelium is a lot more sensitive (detrusor muscle) - that’s the one which is ultimately stretched when you get the urge to pee

64
Q

where does the bladder sit?

A

Just posterior to the pubic symphyses
