Embryology Flashcards
1
Q
Pronephros
A
- week 4
- then degenerates
2
Q
Mesonephros
A
- functions as interim kidney for 1st trimester
- later contributes to male genital system
3
Q
Metanephros
A
- permanent
- appears in 5th week of gestation
- nephrogenesis continues through 32-36 weeks
- ureteric bud: derived from caudal end of mesonephric duct; gives rise to ureter, pelvises, calyces, collecting ducts; fully canalized by 10th week
- metanephric mesenchym: ureteric bud interacts with this tissue; interaction induces differentiation and formation of glomerulus through to distal convoluted tubule (DCT)
