Classification
Nouns denoting body parts.
Examples
- The coelom is a fluid-filled cavity in the embryonic mesoderm that eventually gives rise to several major body cavities.
- During embryonic development, the coelom separates the somatic mesoderm from the splanchnic mesoderm and forms a central cavity.
- The development of the coelom in vertebrates is a complex process involving the folding and compartmentalization of the embryonic tissue.
- In the embryo, the coelom forms as a series of small cavities that eventually fuse to form a single cavity that encloses the developing organs.
- The parietal and visceral layers of the coelom eventually give rise to the lining of the major body cavities, including the pleural, pericardial, and peritoneal cavities.
