Histology Flashcards
kidney capsule is made from
dense collagen
medullary __ point towards hilum = called __
apices
papillae
__ arteries arch over back of renal pyramids
arcuate
renal corpuscle = __+__
Bowmans capsule and glomerulus
bowmans capsule = _ __ epithelium cup
simple squamous
2 cell layers over renal corpuscle capillaries
capillary epithelium
specialised epithelium from podocytes = fenestrated
podocytes have ___ cell processes that form __
interdigitating
filtration slits
scattered mesangial cells in between 2 cell layers covering glomerular capillaries produce a CT core called \_\_\_ function =
mesangium
support and debris removal
prox convoluted tubule : lined by \_\_\_ cell, thats v \_\_\_ has extensive \_\_ and lots of \_\_\_ large \_\_ in centre of cell \_\_\_ at apical end at luminal end = \_\_ to prevent diffusion
simple cuboidal microvilli metabolically active nuclei brush border tight junctions
thin limb of loop of Henle = ___ lining with nuclei that ___
thin simple squamous
protrude into lumen
thick limb of loop of Henle = ___ epithelial cells lining with abundant __
simple cuboidal
mitochondria
vasa recta =
doesnt carry __ away from medulla
thin walled blood vessels that loop from cortex to medulla to cortex
salt
distal convoluted tubule lies in __ of kidney
lined with ___ epithelium
unlike proximal conv tubule lacks a __

simple cuboidal
brush border
collecting duct lies in __ of kidney
run in medullary rays with __+__
= ___ epithelium
cortex
straight segments of proximal and distal tubules
cimple columnar
ducts of Bellini =
fluid = __ at this point as is no longer going to be ___
largest collecting ducts that open into renal papilla
urine
3 components of juxtaglomerular apparatus
macula densa
juxtaglomerular cells
extraglomerar mesangial cells (lacis cells)
macula densa:
on the side of distal convoluted tubule nearest __ arteriole the cells are ++_
function =
afferent
taller, crowded and nuclei intensely stain
sense ion composition in DCT - when Na+ low => renin secretion from juxtaglomerular cells
modified SM cells in wall of afferent arteriole whose function is to contain/secrete renin
juxtaglomerular cells
almost all of minor calyx to urethra is lined by ___
urothelium / transitional epithelium - stratified with 3-6 cell layers
cells at luminal surface of urothelium = __/__ cells
on lumen side they have a special __+__ membrane
umbrella/surface cells
thickened and inflexible
apical surface of urothelium surface cells have a ___ to provide a __
thickened membrane
highly impermeable barrier
below urothelium = ___ and 2-3 layers of __
lamina propria
SM
(histologically) proximal ureter has less ___ and more ___ than distal ureter

lining of female urethra = ___ then ___ near termination
urothelium
stratified squamous
lining of male urethra =
prostatic =
membranous = __-__
penile = __ - __ at penis tip
prostatic = urothelium membranous = urothelium to stratified columnar penile = stratified columnar to stratified squamous at penis tip
prostate glands = ___ glands lined by ____ epithelium and ___ stroma
tubulo-alveolar
simple columnar secretory
fibromuscular
