An egg with 22 chromosomes is fertilized by a normal sperm and the result is an embryo. The process of development takes place in three phases: cleavage, blastulation, and gastrulation. Cleavage involves division to form 2 or more cells. Blastulation happens when the cells migrate to another area of the uterus and then return for differentiation into 3 layers – ectoderm, endoderm, mesoderm. Gastrulation occurs when this 3 layer tissue folds inwardly to create 2 cavities-the archenteron (primitive gut) and splanchnopleure (primitive body cavity). The Development of Eggs and Sperm (cont.) Blastulation happens when the cells migrate to another area of the uterus and then return for differentiation into three layers – ectoderm, endoderm, mesoderm. Gastrulation occurs when this two cavities-the archenteron (primitive gut) and splanchnopleure (primitive body cavity). This process is initially carried out in the womb as a female fetus but it will also be completed after birth by continuing cell division until all body tissues are fully developed. Themes: embryology; development of an organism’s structure from anatomical components Development phases: cleavage, blastulation, gastrtion. Cleavage involves
