Quick Answer. According to the New York University Langone Medical Center, intervertebral discs are made up of fibrocartilage tissue, which has two layers. While the inner portion resembles jelly, the outermost part has strong and fibrous layers. About 90 percent of this tissue is water.
The embryonic disc now lies between the amniotic cavity and the primary yolk sac. Cells from the yolk sac endoderm form a layer of connective tissue, the extraembryonic mesoderm, which surrounds the amnion and yolk sac.he epiblast forms the floor of the amniotic cavity and is continuous peripherally with the amnion. The hypoblast forms the roof of the exocoelomic cavity and is continuous with the thin exocoelomic membrane. This membrane along with hypoblast forms the primary yolk sac.
