Chapter 28, Problem 3A

Summary Introduction

To fill:

The name of a group of cells that develop from the nerve cord in vertebrates.

Introduction:

Animals belonging to the subphylum vertebrate are called vertebrates. Vertebrates have a spinal column and specialized cells that grow from the nerve cord. The spinal column is also called the spinal cord. The vertebral column is the symbol of the vertebrates. Vertebrates include fish, reptiles, mammals, amphibians and birds.

Answer to Problem 3A

A group of cells that develop from the nerve cord in vertebrates is called a neural crest.

Explanation of Solution

As the nerve cord develops during embryonic development in vertebrates, there is another phase called neural crest develops. The neural crest is a group of cells that develop in vertebrates from the nerve cord. Although the cell group is small, it is significant in the development of vertebrates because many important vertebrates develop from the neural crest.

Conclusion

A group of cells that develop from the nerve cord in vertebrates is called a neural crest.
