Summary Introduction

To review:

Segmentation of body parts that allow things to function.

Introduction:

The word segmentation in biology refers to the division of animal parts as a repeating unit. The proof of segmentation is found in the vertebral column ribs (backbone) and its associated muscles, in humans and in other vertebrates. It is found in the mesoderm, which forms most of the body bulk during the development and sometimes can also be depicted in the structures of ectoderm and endoderm. For instance, the ring line pattern on earthworms.
