EMBRYOLOGY

A complex morphogenetic process by which embryonic tissue is restructured to converge along one axis and extend along a perpendicular axis by cellular movement.

During convergent extension, cells elongate, move mediolaterally, and intercalate between neighbouring cells, thus converging toward a mediolateral axis and extending along an anteroposterior axis. The process of convergent extension occurs in gastrulation, neurulation, axis elongation, and organogenesis in vertebrate and invertebrate embryos and plays a central role in shaping the body plan during embryogenesis.
