Renal Histology

Question 0

what is histologically unique about the glomerular capillaries?

Answer 0

only fenestrated capillaries without a diaphragm

Question 1

what makes up the visceral epithelium of bowman’s capsule?

Answer 1

podocytes

Question 2

what makes up the parietal epithelium of bowman’s capsule?

Answer 2

flattened squamous cells

Question 3

endocrine cells next to the afferent arterial (juxtaglomerular cells) synthesize and secrete ____

Answer 3

renin

Question 4

dark staining cells near the juxtaglomerular cells on the distal convoluted tubule

Answer 4

macula densa

Question 5

what’s unique about the juxtaglomerular nephrons in terms of capillaries?

Answer 5

vasa recta

Question 6

little processes that come off the major processes of podocytes

Answer 6

foot processes, pedicells

Question 7

in between the processes of podocytes are ____

Answer 7

filtration slits

Question 8

cells that are between the endothelial cells, involved in phagocytosis

Answer 8

mesangial cells

Question 9

which one can be seen at the light microscopic level: basal lamina or basement membrane?

Answer 9

basement membrane

Question 10

are filtration slits covered by a diaphragm?

Answer 10

yes

Question 11

why are foot processes so dark?

Answer 11

they are filled with actin

Question 12

nephrotic syndrome

Answer 12

the membrane of bowman’s capsule breaks down and you get protein leaking in, leading to proteinuria
