Blastocoel (Noun)
Meaning
The fluid-filled cavity inside a blastula.
Classification
Nouns denoting animals.
Examples
- The blastocoel is the fluid-filled cavity inside the blastula, a critical structure during early embryonic development in many animals.
- In the blastula stage, cells form a hollow sphere surrounding a blastocoel, which helps embryonic cells disperse or enter specific developmental pathways.
- A key characteristic of the blastula is the fluid-filled cavity known as the blastocoel, from which further cell growth and cell migration will occur.
- During embryonic development, cells start migrating away from the blastocoel, leading to the formation of a gastrula, the next developmental stage.
- The blastocoel's dimensions are linked to embryo developmental stages, as changing size can signal the end of the blastula stage and onset of gastrulation.
