Question
Chapter 52, Problem 5U
Summary Introduction
The process of organogenesis in vertebrates begins with the two features such as notochord and the hollow dorsal nerve cord. The neural tube is formed from ectoderm cells, and the rest of the body is developed by changes in the mesoderm. The notochord is also formed from mesoderm
