Kidney embryology Flashcards
What two ductal structures develop in both male and female embryo
Wolffian/ Mesonephric ducts
Paramesonephric/ Mullerian ducts
Where does mesenchyme run on the embryo
On either side of the embryo
How do the ducts behave in female embryos
Mesonephric duct degenerates apart from lower portion which forms uteric bud
Paramesonerphic duct forms oviduct
How do ducts behave in male embryo
Mesenophric duct forms the male reproductive truct and uteric bud
Paramesonephric duct degenerates
How many kidney develop in the embryo
3
What is the final, fully developed kidney called
Metanephric kidney
What kidney do you start off with embryo-logically
Pronephric kidney
Which two embryological kidneys form a duct system
Pronephric
Mesonephric
Where are all 3 embryological kidneys formed from
Mesonephric duct
What 2 embryonic structures is the metanephric kidney derived from?
Uteric bud from mesonephric duct
Metanephric bud derived from mesenchyme
What is the site called where uteric bud comes into contact with mesenchyme
Metanephric bud
What is derived from the uteric bud?
- Uterer
- Renal pelvis
- Major and minor calices
- Collecting tubules
What is derived from metanephric bud
- Glomerulus and capillaries
- Bowmans capsule
- PCT
- Loop of henle
- DCT
How many collecting tubules are found in kidney
1-3 million
What do the major calyces bifurcate to form
Minor calyces
What do minor calyces split to form
Collecting tubules
What happens when mesenchyme comes into contact with the collecting tubule
It elongates
What happens once the kidney has formed
It ascends within the embryo
What happens as kidney grows and enlarges
It open out and moves upwards within embryo until it reaches final resting region
Where does metanephros develop
