Urinary System(manual based) Flashcards
Two parts of the kidney
Outer renal cortex & Inner renal medulla
Lamina propia of kidney’s capsule
DICT
Shape of renal corpuscles
Spherical/rounded structures
Tufts of fenestrated capillaries
Glomerulus
Layer of BC wherein podocytes are adjacent to glomerulus; difficult to visualize under microscope
Visceral layer
Lining epithelium of parietal layer of BC
Simple squamous epithelium
Space between the visceral and parietal layer
Bowman’s space
Rounded profiles of varying sizes
PCT & DCT
Lining epithelium of PCT & DCT
Simple cuboidal epithelium
Which is longer PCT/DCT?
PCT
________ Has a clear distinct apical border while __________ have brush border
DCT & PCT
Lesser nuclei is seen in the cross section of
PCT
More nuclei is seen in the cross section of
DCT
Has a more acidophilic cytoplasm
PCT
The lumen of the _____ is small and often star shaped
PCT
Lumen of _______ is wider
DCT
Found in between the renal corpuscle , PCT and DCT; composed of tubules oriented in the same direction, traveling a straight course to or from the medulla
Medullary ray
Component of the medullary ray
Proximal descending limb of the loop Henle, Distal ascending limb of the loop of Henle, collecting tubules
JG cells are found where
Cortex
Parts of the DCT that lie adjacent to the vascular pole will show crowding nuclei
Macula densa
Entry of afferent arteriole and exit of the efferent arteriole to and from the renal corpuscle
Vascular pole
Modified smooth muscle cells of the afferent arteriole
Juxtaglomerular cells
Surrounding the glomerulus
Mesangial cells
Consists of conical shaped structures called as _________.
Renal medulla, renal pyramids
______ of the pyramid faces the cortex and the _______ towards the hilum of the kidney
Base, Apex
Lining epithelium of collecting tubules
Simple cuboidal epithelium
Lining epithelium of collecting ducts(ducts of Bellini)
Simple columnar epithelium
*both collecting tubules and ducts show prominent cell boundaries
LE of descending limb of Henle
Simple cuboidal w/ brush border
LE of the thin limb of henle
Simple squamous epithelium
LE of ascending limb of Henle
Simple cuboidal epithelium w/ no brush border
LE of vasa recta(BV)
Simple squamous epithelium
To distinguish thin limb of loop of Henle from The vasa recta
- RBC can be seen in the lumen of vasa recta
- Squamous cells lining the thin limb have a spherical nuclei which bulge into the lumen while the endothelial cells of the vasa recta are flat
Lumen of the female urethra
Crescentic lumen
What does the mucosa of the female urethra possess
Longitudinal folds
LE of female urethra
Initial= Transitional Midportion= pseudo/stratified columnar epithelium Termination= stratified squamous
LP of female urethra
LCT & branched tubular(urethra) glands
Muscularis layer of Female urethra
Thicker smooth muscle layer
Thick muscular wall
Urinary bladder
Mucosa of urinary bladder
Thrown into folds
UB mucosal cells: cuboidal/columnar eosinophilic cytoplasm
Basal cells
UB mucosal cells: polygonal, eosinophilic cytoplasm
Intermediate cells
UB mucosal cells: large ovoid, 1 or 2 nuclei; eosiniphilic cytoplasm; gives scalloped appearance mucosa
Surface cells/umbrella cells/dome cells
Lamina propia of urinary bladder
Loose and dense connective tissue
Muscularis of UB is made up of 3 ill defined layers of smooth muscle
Detrusor muscle
Adventitia of UB
LCT; serosa present only in the superior surface
