| | Key Points (from Dutta) | |-----------|-----------------------------| | Gametogenesis | Spermatogenesis (74 days) + Oogenesis (arrested at Prophase I until puberty). | | 1st week of development | Fertilization → Zygote → Morula (day 3) → Blastocyst (day 5) → Implantation (day 6-7). | | 2nd week | Bilaminar germ disc: Epiblast + Hypoblast. Formation of amniotic cavity & yolk sac. | | 3rd week (Gastrulation) | Primitive streak → Three germ layers (Ectoderm, Mesoderm, Endoderm). Notochord forms. | | 4th–8th week (Organogenesis) | Neural tube closure (day 22-28) → most critical for neural tube defects. | | Fetal period | 9 weeks – birth. Major growth & maturation. | | Placenta | Decidua basalis + chorionic villi. Functions: exchange, barrier (partial), hormones (hCG, estrogen, progesterone). | | Common congenital anomalies | Cleft lip (week 4-7), spina bifida (neural tube fails to close), cardiac defects (week 5-8). | This is Dutta’s masterpiece
