Blastopore (Noun)
Meaning
The opening into the archenteron.
Classification
Nouns denoting animals.
Examples
- The blastopore is the opening into the archenteron, a primitive gut that forms during the early stages of embryonic development.
- During gastrulation, the blastopore invaginates to form the archenteron, which eventually gives rise to the digestive system.
- In some species, the blastopore is initially located at the posterior end of the embryo, but later migrates to the anterior end.
- The blastopore is formed when the cells at the surface of the blastula invaginate to create the archenteron, a process that is crucial for the formation of the embryonic gut.
- The size and shape of the blastopore can vary greatly between different species, but its function as the opening into the archenteron remains the same.
