Folding of embryonic disc
WebThe process of cephalocaudal and lateral folding that transforms the embryo from a flat disc to a three-dimensional vertebrate body form. As folding occurs, the embryo grows … WebFolding of the embryonic disc occurs ventrally around the notochord, which forms a rod-like region running rostro-caudally in the midline. Folding of the ecoderm will form a neural groove, then closing to form a neural tube, separating the neural ectoderm from the embryo surface ectoderm. Mesoderm Segmentation
