Embryology: Cleavage, Blastulation & Implantation | First Week of Human Development Explained

In this detailed VB Anatomy embryology lecture, you will clearly understand the complete journey of the embryo during the first week of intrauterine life, from fertilization to implantation. ✅ What you will learn in this video: How the fertilized ovum in the ampulla of uterine tube travels toward the uterus for implantation Key introductory definitions: zygote, embryo, fetus, neonate, and infant The entire first week explained stepwise through 4 major stages: Cleavage division Morula formation Blastocyst formation Implantation into endometrium ✅ Cleavage and Early Divisions Explanation of cleavage division and formation of blastomeres Role and clinical importance of the zona pellucida (commonly asked short note) ✅ Morula Stage How the embryo continues moving toward the uterine cavity Formation of the morula and differentiation into: Inner cell mass Outer cell mass ✅ Blastocyst Formation (Blastulation) Development of the fluid-filled cavity (blastocoel) Detailed structure and parts of the blastocyst Quick revision through a tabular summary ✅ Implantation (Day 6) Stepwise explanation of implantation into the endometrium Loss of zona pellucida and readiness of uterus in secretory phase Attachment and reorientation of blastocyst Formation of trophoblastic layers: Syncytiotrophoblast Cytotrophoblast ✅ Formation of Bilaminar Disc Division of inner cell mass into: Epiblast Hypoblast ✅ Clinical and Applied Importance High-yield applied aspects related to the first 7 days of development Encouragement to continue into Second Week of Embryology 🎓 Ideal For: First MBBS, BDS students Physiotherapy, Ayurveda, Homeopathy students Third-year MBBS students studying Gynaecology Early residents in Obstetrics & Gynaecology 📚 REFERENCE VIDEOS — Fertilization & Gametogenesis Fertilization Series 1️⃣ Fertilization: Part 1    • Fertilization: Part 1   2️⃣ Fertilization: Part 2    • Fertilization: Part 2   3️⃣ Fertilization: Part 3    • Fertilization: Part 3   Gametogenesis 🍏 Spermatogenesis    • Spermatogenesis | Step-by-Step Process Exp...   🍎 Oogenesis – Part 1    • Oogenesis Part 1 | Journey from Primordial...   0:00 – Introduction: What this video covers 1:11 – What is a zygote, embryo, and fetus? 4:03 – Cleavage division 5:06 – Formation of morula 6:22 – Inner cell mass and outer cell mass formation 8:12 – Blastocyst formation 10:53 – Quick revision (tabular summary) 11:36 – Implantation of blastocyst 12:47 – Short note on zona pellucida 15:51 – Orientation and adhesion of blastocyst to endometrium 16:47 – Trophoblast penetration: Syncytiotrophoblast & Cytotrophoblast formation 18:33 – Formation of epiblast and hypoblast
