Embryology of the Digestive and Urinary System

Embryology · Basic Sciences

How it begins

An exhaustive journey from the folding of the trilaminar embryo to the functional maturation of the digestive tract and urinary system, with emphasis on morphogenetic mechanisms, epithelial-mesenchymal interactions and congenital malformations of clinical relevance.

What it covers

1. Introduction: from the trilaminar disc to the cylindrical embryo
2. Germinative layers and derivatives of the endoderm
3. The primitive intestinal tube: division and vascularization
4. Digestive System
5. Foregut: pharynx, respiratory system and septum
6. Esophagus and stomach: elongation, rotation and formation of the omentum
7. · Esophagus
8. · Stomach: the two rotations
9. Duodenum, liver, gallbladder and pancreas
10. · Duodenum
11. · Liver and bile ducts
12. · Pancreas: two outlines, one gland
13. Middle intestine: herniation, rotation and return
14. Hindgut, cloaca and anal canal
15. Mesenteries, peritoneum and retroperitoneal organs
16. Synthesis of digestive clinical correlations
17. Urinary System
18. The intermediate mesoderm and the nephrogenic cord
19. The three kidney generations
20. Metanephros: reciprocal induction and nephrogenesis
21. Ascent, rotation and change in renal irrigation
22. Bladder, urethra and destination of the urogenital sinus
23. Synthesis of urinary clinical correlations
24. Integration: the sewer as a crossroads
