For those writing the make-up exam, she needs to see you at break today, will call down the list. Another list at break, and will call down then. Morphogenesis is key for growth, tissue interaction and organ formation during development. It is a complex thing and is hard to cover in one class. Morphogenesis is one of the three (3) fundamental stages of development. Gastrulation reorganizes the blastula and it is the most important time of life. In folding of the embryo is done to create the endoderm, mesoderm and ectoderm, these are the three (3) most important layers. The cells that are far apart at one point are now close together. This allows cells to interact with other layers. Internal epithelial cell (iec) layer and mesenchymal cell layer (mes). Internal epithelial cells line the internal layer of ducts that develop into organs and other tissues. Mesenchymal cell layer forms the connective tissue and has a blood supply.
