Document Summary
Epidermis is made from ectoderm, it is the outer epithelial layer of the embryo. The neural plate is formed when the ectoderm on the dorsal plate thickens antherioraly from the primitive node. Give two examples (one could be d-v specification in drosophila; go back and check). Bone morphogenic proteins is expressed on the ventral side, which induces the ectoderm to become epidermis. Inhibitor bmp are used to inhibit ectoderm to become epidermis and allow neural tissues to form: define neurulation. List four stages of primary neurulation in chick embryo. Neuralation is the signaling of the mesoderm to the cells of the ectoderm, just above. It is when the cells from the neural plate form the neural tube. The cells are derived anterior from the hensens node and the node itself. The medial hinge points are the cells at the midline is used for bending.
