Document Summary
Developmental biology deals with the development of a the circle of live single cell to a complete organism the central question can be subdivided into: differentiation, Differentiation: addresses the cellular level of an organism -> at least 250 distinguishable cell types in the human body: morphogenesis: formation and development of different organs. Growth: controlled dividing of the organism"s cells into a reasonable size. Regeneration: the ability to regrow damaged tissue, organs or cells. Evolution: undirected mutation causes genetic pool change, which might be beneficial and given to offspring (1) fertilization: merging of the haploid nuclei of sperm and egg -> Cytoplasmic movements , determining body axes (2) cleavage: first series of rapid mitotic divisions -> no growth in weight (3) Gastrulation: drastic cell movements, rearrangement of embryo -> formation of the germ layers: ectoderm, endoderm, Malformation: abnormalities caused by genetic events (mutations, chromosomal applications in agriculture and industry aneuploidies) -> trisomy 21, siamese twins, piebaldism stem cells cancer.
