gastrulation

Thân thiện

During gastrulation, the embryo's cells migrate inward to form distinct layers.

Definition

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.

Usage Examples

• 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.

Advanced Usage

• "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.

Variants and Related Words

• 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 .")

Synonyms

• 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.)
