Compare the role of notochord in the early development of vertebrates and invertebrates.
Describe the development of the notochord. Include the terms primitive pit, notochordal process, notochordal canal, neurenteric canal, notochordal plate, ectoderm, mesoderm, and endoderm in your descriptions. Include labeled diagrams in your description. With respect to the developing notochord, where is the cloacal membrane, allantois, embryonic ectoderm, embryonic endoderm, and embryonic mesoderm with reference to the developing notochord.
Define the following terms with respect to mammalian development
