blastocoel
Definition
- Noun:
- The fluid-filled cavity inside a blastula: A blastocoel is the central, hollow cavity filled with fluid that forms during the early embryonic development of many animals, specifically within the structure called a blastula.
Usage Examples
- Noun:
- The blastocoel forms as cells divide and rearrange during cleavage.
- Researchers observed the expansion of the blastocoel under the microscope.
- The fluid pressure within the blastocoel helps maintain the blastula's spherical shape.
Advanced Usage
- "blastocoel formation": the developmental process by which the cavity is created.
- The timing of blastocoel formation is a critical stage in embryogenesis.
- "blastocoel fluid": the specific liquid contained within the cavity.
- The composition of the blastocoel fluid differs from the surrounding cellular environment.
Variants and Related Words
- Blastocoele (n): An alternative spelling for blastocoel.
- Blastula (n): The early embryonic stage, typically a hollow ball of cells, within which the blastocoel forms.
- Blastocyst (n): In mammalian development, a later stage structurally similar to a blastula, featuring a blastocoel-like cavity.
Synonyms
- Segmentation cavity: A synonym emphasizing the cavity's formation during the cleavage (segmentation) stage.
- Cleavage cavity: Another synonym highlighting its appearance during the cell division process of cleavage.
Related Terms (Conceptual)
- Gastrulation: The developmental stage following the blastula stage, during which the blastocoel is often reduced or eliminated as new layers form.
- Archenteron: The primitive gut cavity that forms during gastrulation, which is distinct from and often replaces the blastocoel.
Noun
-
