Webmovements, emboly/internalization, epiboly, convergence, and extension, which are deﬁned by their morphogenetic outcome (Keller et al. 1991). Emboly, or internalization, is the deﬁning gastrulation movement, which transports the prospective mesodermal and endodermal cells beneath the future ectoderm (Figure 1a–j). Epibolic movements spread Web2005). Epiboly represents the spreading of embryonic cells over a vegetal yolk mass, resulting in ectoderm to cover the embryo. Emboly (ingression, involution, invagination) relocates the mesendodermal anlagen into the inner embryo. Convergence of vegetal and lateral cells to the dorsal axis and extension establish the long axis of the embryo.
