Renal Histology Flashcards
What are the two types of nephrons?
Cortical
Juxtamedullary
How permeable is the bladder epithelium?
Not at all
What epithelial types does the urethra have?
Transitional
Stratified squamous
T/F the distal tubule have microvilli?
False
What forms Bowman’s capsule?
The end of the tubule that comes around and encapsulates the glomerulus
What part of the kidneys have the pyramids?
Medulla
What is between the capillaries and Bowman’s capsule?
Bowman’s space
What is the different between podocytes and mesangial cells?
Podocytes are specialised epithelial cells
Mesangial cells are smooth muscle cells
What is the name of the sphincter of the urethra?
External urethra sphincter
What type of cells are in the proximal tubule?
Simple cuboidal cells
What type of cell lines the ureter?
Transitional epithelium
Where in the renal system is lined by transitional epithelium?
Ureter
Bladder
First part of urethra
Which have a large lumen, the proximal or distal tubule?
Distal
What is unique of the lumen of the collecting duct?
It is larger
Where are renal corpuscles located?
In the cortex of the kidney
What is the name of the cells that produce renin and that the macula densa communicates with?
Juxta-glomerular cells
T/F the glomerulus is the capillaries only
True
What is the name of the outer part of the kidney?
Cortex
Describe the macula densa cells
Condensed and regularly alined
What feature do the epithelials of the proximal tubule have?
Brush border with long microvilli
What is the structure of podocytes?
They surround glomeruli capillaries and give up interdigitating fingers (pedicles) that assist in filtration
What type of cell make up the wall of the thin loop of Henle?
Simple squamous cells
What is the name of the cells the surround the capillary of the glomerulus and provide support and filtration?
Mesangial cells
Podocytes
Which has more mitochondria, the proximal or distal tubule?
Distal
What is the difference between interlobular vessels and interlobar vessels?
Interlobular are given off at right angles to the arcuate vessels while interlobar run in between medulla towards the cortex
What is the name of the vessels that lie at hte boundary of the cortex and medulla?
Arcuate vessels
T/F there is peristalsis in the ureter
True - regulated by autonomic nerves
Describe the epithelials of the collecting duct
More columnar, cuboidal cells
