Notes de l'éditeur
- Intermediate mesoderm on either side of the dorsal body wall/notochord gives rise to 3 successive nephric structures of increasingly advanced design
- Pronephroi- nonfunctional segmental nephrotomes which develop in cervical region-represent a vestige of primitive kidneys seen in lower vertebrates, begin to appear at 24 days and regress in the fourth week Mesonephros – initial appearance of mesonephros and mesonephric duct at 25 days. Metanephric blastema and metanephric ducts appear at 28 days or end of week 4 Mesonephros develop in thoracic and lumbar regions during 4 th week, functional with complete but simple nephrons drained by the mesonephric (Wolffian Ducts) Nephric ducts grow caudally to open into the posterior wall of the primitive urogenital sinus by week 5 Metanephroi-definitive kidneys begin to form during 5 th week by induction of sacral intermediate mesoderm by UBs
- UBs sprout from the distal end of the mesonephric duct by week 5
