METAGASTRULA Meaning and
Definition
-
Metagastrula is a developmental stage observed in the early embryonic development of some animals. It refers to a specific stage in the process of gastrulation, which is the process by which a single-layered blastula transforms into a multi-layered embryo.
At the metagastrula stage, the embryo has undergone a complex series of cellular movements and differentiations, resulting in the formation of three primary germ layers: the ectoderm, endoderm, and mesoderm. These germ layers give rise to the various tissues and organs in the adult organism.
During metagastrulation, the embryo goes through a process called gastrulation, where the cells in the blastula rearrange and migrate to form the three germ layers. This process involves invagination, where some cells fold inward, forming a cavity known as the archenteron. The cells that form this cavity become the endoderm, while the cells on the exterior become the ectoderm. In some organisms, a third layer, the mesoderm, also forms between the endoderm and ectoderm.
Metagastrula represents an important stage in embryonic development, as it marks the beginning of the formation of the body plan and sets the stage for the subsequent development of organs and tissues. It is a critical step that lays the foundation for the future structure and functions of the adult organism.

Etymology of METAGASTRULA
The word "metagastrula" is a combination of two terms: "meta-" and "gastrula".
The prefix "meta-" in Greek means "beyond" or "after". It is often used to denote a higher level or a subsequent stage in a sequence.
The word "gastrula" comes from the Greek word "gaster" which means "stomach" or "belly". In embryology, the gastrula is a stage in the early development of an animal embryo. It follows the blastula stage and involves the formation of three germ layers that will give rise to different tissues and organs.
Therefore, when combined, "metagastrula" refers to a stage beyond or after the gastrula stage in embryonic development.
