Blastocoele (Noun)
Meaning
The fluid-filled cavity inside a blastula.
Classification
Nouns denoting animals.
Examples
- The blastocoele is a fluid-filled cavity that forms inside the blastula during the early stages of embryonic development.
- In many species, the blastocoele is the first visible sign of the formation of a cavity within the embryo.
- The blastocoele is surrounded by a layer of cells called the blastoderm, which will eventually give rise to the three primary germ layers.
- During gastrulation, the blastocoele is gradually obliterated as the cells of the blastoderm begin to invaginate and form the embryonic gut.
- The size and shape of the blastocoele can vary significantly between different species, reflecting differences in their developmental biology.
