Explanation

Number of cells of epiblast pass through the primitive streak, move laterally into the blastocoel to form a new layer of cells, called mesoderm. The mesoderm is one of the three primary germ layers that form during early embryonic development in animals. The other two primary germ layers are the ectoderm and the endoderm. These three germ layers give rise to the various tissues, organs, and systems of the body.During gastrulation, which follows the blastula stage in embryonic development, some cells in the developing embryo migrate to the middle layer. This middle layer becomes the mesoderm. The mesoderm is situated between the outer ectoderm and the inner endoderm.The mesoderm plays a central role in the development of the body's musculoskeletal system and is crucial for the formation of organs and structures responsible for support, movement, and transport, such as the circulatory system. It also gives rise to connective tissues that support and connect various organs and structures within the body.The mesoderm, in conjunction with the ectoderm and endoderm, is essential for the development of a wide range of tissues and organs during embryogenesis. It is responsible for creating the structural framework of the body and the various systems that allow for movement, circulation, and other essential physiological functions.
