| Description: About 16 days after fertilization, the notochordal process forms. By days 22–24, the process becomes the solid cylinder called the notochord. The notochord is important for induction, the process whereby the inducing tissue stimulates development of a responding tissue to develop into a specific structure. The notochord induces the development of vertebral bodies and the nucleus pulposus of vertebral discs.
