What is the convergent extension? What does CONVERGENT EXTENSION mean? Biology Ikqra Convergent extension during Gastrulation/dorsal blastopore Frog development |Biology |IQ learning The process by which the tissue of an embryo is remodelled to converge (narrow) along one axis and extend (elongate) down a perpendicular axis through cellular movement is known as convergence extension (CE), sometimes known as convergence and extension (C&E). An illustration of this process is when the lateral tissues, which make up the left and right sides of the embryo, move inward toward the dorsal midline, lengthening the anteroposterior axis (the axis drawn between the head and tail end of an embryo) (the middle of the back of the animal). This process, which takes place in both vertebrate and invertebrate embryos during gastrulation, neurulation, axis elongation, and organogenesis, is essential for determining the body plan throughout embryogenesis.
