Germ Layers & Vertebral Development * Vertebrae develop from sclerotome, a derivative of the paraxial mesoderm (somites). * Failure of complete formation or segmentation of the sclerotome leads to hemivertebra, an important cause of congenital scoliosis. * Ectoderm forms skin and nervous system structures * Endoderm forms intestinal epithelial linings * Notochord does not form
