Flashcards in developement Deck (10):
What are the three sequential sets of kidneys
pronephros, mesonephros, metanephros
what are the two primordia of the UG system
intermediate mesoderm, splanchnopleure of hindgut
The intermediate mesoderm bulges into the peritoneal cavity to form what two things? Together called?
nephrogenic cord, gonadal ridge. Together called urogenital ridge
Paramesonephric ducts: where do they develop? what do they develop into?
in-foldings of nephrogenic cord. Become uterus, uterine tubes, upper vagina
mesonephric duct. What? where does it connect?
embryonic ureter. Joins the mesophrc tubules and drains to cloaca
aka ureteric bud. originates from mesonephric duct but makes its own connection to cloaca
what are the two primordia of the metanephros? what do they give rise to?
ureteric bud: ureters, renal pelvis, calyces, collecting ducts and tubules, metanephric mass of intermediate mesoderm: nephrons
where is the union of the ureteric bud and metanephric mesoderm?
b/w the DCT (mesoderm) and the collecting tubule (bud)
horseshoe kidney arises from what?
fusion of ureteric buds that hood around inferior mesenteric artery
