gastrulation
Noun: 1. A key stage in early embryonic development: Gastrulation is the biological process during which a single-layered blastula reorganizes into a multilayered structure called a gastrula. This involves the coordinated movement and inward migration of cells to form the primary germ layers (ectoderm, mesoderm, and endoderm), which will give rise to all tissues and organs of the organism.
- Noun:
- Gastrulation is a critical and highly conserved phase in the development of most animals.
- During gastrulation, cells move inward to form the primitive gut.
- The precise timing of gastrulation varies between different species.
- "to undergo gastrulation": to experience or proceed through the gastrulation process.
- The embryo must successfully undergo gastrulation for proper development to continue.
- "gastrulation defects": abnormalities or failures in the gastrulation process.
- Gastrulation defects often lead to severe developmental disorders.
- Gastrula (n): The embryonic structure formed as a result of gastrulation, typically consisting of two or three germ layers.
- Blastula (n): The hollow ball of cells stage that precedes gastrulation.
- Gastrulate (v): To undergo the process of gastrulation. (e.g., "The cells begin to .")
- Embryonic layer formation: (A descriptive synonym referring to the outcome of the process.)
- Germ layer specification: (A related term emphasizing the establishment of the germ layers.)
(Note: As a highly specific scientific term, "gastrulation" does not have phrasal verbs or idioms in common usage. The phrases below are common collocations in developmental biology.) - Onset of gastrulation: The beginning of the gastrulation process. - Completion of gastrulation: The point at which the gastrulation process is finished and the gastrula is formed.
-
the process in which a gastrula develops from a blastula by the inward migration of cells
