- Gastrulation - Wikipedia
Gastrulation is the stage in the early embryonic development of most animals, during which the blastula (a single-layered hollow sphere of cells), or in mammals, the blastocyst, is reorganized into a two-layered or three-layered embryo known as the gastrula [1]
- Gastrula | Embryology, Cell Differentiation Morphogenesis . . .
gastrula, early multicellular embryo, composed of two or more germinal layers of cells from which the various organs later derive The gastrula develops from the hollow, single-layered ball of cells called a blastula which itself is the product of the repeated cell division, or cleavage, of a fertilized egg This cleavage is followed by a
- Gastrulation - Definition and Types - Biology Dictionary
Gastrulation is the process during embryonic development that changes the embryo from a blastula with a single layer of cells to a gastrula containing multiple layers of cells Gastrulation typically involves the blastula folding in upon itself or dividing, which creates two layers of cells
- 43. 5B: Cleavage, the Blastula Stage, and Gastrulation
After the cleavage has produced over 100 cells, the embryo is called a blastula The blastula is usually a spherical layer of cells (the blastoderm) surrounding a fluid-filled or yolk-filled cavity (the blastocoel)
- Embryology - Cellular Division - Gastrulation - TeachMeAnatomy
Gastrulation is a process of cellular rearrangement which involves migration, invagination and differentiation of the epiblast It is largely controlled and orchestrated by the primitive streak The primitive streak is a groove in the midline of the epiblast which appears during the third week
- Embryology, Gastrulation - StatPearls - NCBI Bookshelf
Gastrulation is an early developmental process in which an embryo transforms from a one-dimensional layer of epithelial cells, a blastula, and reorganizes into a multilayered and multidimensional structure called the gastrula
- GASTRULA Definition Meaning - Merriam-Webster
The meaning of GASTRULA is an early metazoan embryo in which the ectoderm, mesoderm, and endoderm are established either by invagination of the blastula (as in fish and amphibians) to form a multilayered cellular cup with a blastopore opening into the archenteron or by differentiation of the blastodisc (as in reptiles, birds, and mammals) and
