The Process of Gastrulation in Frog Embryos
MetadataShow full item record
Illustration of the movement of the three hemispheres of cells, the animal cap (dark green) the marginal zone (lime green) and the ventral cap (yellow) during frog gastrulation. The external view column (images a.1-a.6) shows gastrulation as it occurs on the outside of the embryo. The cross-section view column (images b.1-b.6) shows the internal view of gastrulation. The cross-sections are through the middle of the embryo.
Object is a digital image that diagrams the process of gastrulation in a frog (Xenopus laevis) embryo. The object has six extrenal views and six internalviews of a developing gastrula, one image each for six stages.StageName: 9StageName: 10StageName: 11StageName: 12
