Explanation The neurulation is the process of formation of the neural tube which is a flexible rod present along the dorsal midline on the embryos of all the chordates and acts as supporting structure of the vertebrate’s body. The neural tube forms from ectodermal cells and is therefore called neurulation. It further divides to form parts of the nervous system...

Chapter 52.4, Problem 2LO

Summary Introduction

To determine: The process of neurulation and somatogenesis.

Introduction: The zygote undergoes the process of cleavage where the furrow is formed which is accompanied by cell divisions. Following the cell cleavage, the zygote develops into a hollow mass of cells called the blastula. The blastula then divides to convert into a solid ball of cells called the gastrula, this stage forms the three germ layers called the mesoderm, endoderm, and ectoderm. This process is called gastrulation.
