Development of general body form and early features
As a result of Gastrulation, the embryonic part of the gastrula consists of a flat structure in addition to the formation of three basic germ layers. The basic body pattern in adult vertebrate is found to have one tube within another, the outer being synonymous with the body wall the inner being the digestive tube.
The space between the two is the coelomic cavity. Therefore, in order to achieve the adult body pattern, the early embryo must undergo developmental processes that transform it from a flat structure to a tubular one. These processes begin shortly after the first somites appear and initially take place in the future head region of the embryo.
