Slide2Fertilization occure in the ampulla of the fallopian tube
Then division into
morula while in the fallopiam tubeThen blastocyst moves into uerus and impalnts: embedding into the decidua to get blood supply and nutritionThe inner cell mass differentiates and forms outer(ectodermal layer) and inner (endodermal layer), between them the mesodermal layer
Development of the embryo
Slide3Two small cavities appear one in the ectoderm forms amniotic sacAnd one in the endoderm forms Yolk sac
The two small spheres covered by mesoderm, move into the middle of the blastocyst cavity , the mesoderm form the connecting stalk with future umbilical cord
The 2 opposing layers of ectoderm and endoderm with the mesoderm in between form the actual embryoExpansion of the amniotic sac takes place and the yolk sac disappears
Slide4Slide5Within the embryo the vessels in the cephalic end differentiates to form the heart followed by fetal blood cells formation
Slide6Ectoderm: skin, hair, Nervous system,pituitary gland, salivary glands
Endoderm: Gastrointestinal tract, Liver, pancreas , respiratory tract , germ cells
Mesoderm: Bone muscle cartilage, cardiovasular system, connective tissue, genital tractStructures derived from the primay layers
