Segmentation Cavity (Noun)
Meaning
The fluid-filled cavity inside a blastula.
Classification
Nouns denoting animals.
Examples
- The segmentation cavity formed within the blastula undergoes rapid expansion and is later lined with the newly formed blastoderm cells.
- A major role of the segmentation cavity is to contribute to the movement and morphogenetic patterning of cells within the embryo.
- Formation of the segmentation cavity begins as fluid starts accumulating in the central cavity between the two-cell and the 8-cell stages.
- Molecular analyses indicate that formation of the segmentation cavity within the embryo results in production of highly folded embryonic layers.
- Throughout early development the segmentation cavity supports many biological functions as well as containing signaling proteins required for various aspects of pattern specification.
