Explanation

Muscles, axial skeleton and connective tissue arises from epimeres. Epimeres are segments or regions found in the embryonic development of some animals, particularly invertebrates like arthropods. In arthropods, the mesoderm, which is one of the three primary germ layers in early embryos, can be divided into different regions, with epimeres being one of them. Epimeres and hypomeres together make up the segmental organization of the mesoderm in these animals. In certain animals, such as arthropods (insects, arachnids, crustaceans), the mesoderm is divided into epimeres and hypomeres. The epimeres are the dorsal or upper portions of these mesodermal divisions.The presence of epimeres contributes to the segmental or metameric organization that is typical of arthropods. Each epimere is associated with a specific body segment, and it plays a role in the development of structures associated with that segment.The specific organization and roles of epimeres can vary among different groups of arthropods. For example, in insects, epimeres are involved in the development of dorsal muscles, which play a role in the insect's locomotion and movement.
