Document Summary
Somatopleure membrane wall (parietal), made of somatic mesoderm and ectoderm: close to epidermis, Splanchopleure organ membrane (visceral), made of mesoderm and endoderm: closet endodermal structures. S14,15,18, p452,447: factors for specification mesodermal -> cardioblast, wnt, bmp, fgf, factors for determination cardioblast -> cardiomyocyte (induce heart-specific proteins, nkx2-5, gata. Notch signalling pathway activated by vegf: stimulates gridlock to activate ephrin for blood vessel formation. 4: during the formation of the circulatory system, arterial and venous capillaries connect. Biol 303 study questions for lecture 13, 14 aaron exclusively to each other. L14s22: digestive tube, respiratory tube, epithelial lining digestive, respiratory, name three organs that develop as outgrowths of the early digestive system and name one function for each of these organs. For each of these adaptations state the germ layer origin(s) and the environmental problem it targets. Nutrition: general question: cells make multiple transitions during development between epithelial and mesenchymal states. There are also many examples of communication between epithelial and mesenchymal structures.
