True about notochord are all except?
Notochord is a bud like structure formed by epiblast cells extending from cranial end of primitive streak to caudal end of prochordal plate, in between the ectoderm and endoderm. Siginificances of notochord includes following :-It defines the axis of embryo.It functions as the primary inductor, inducing the overlying ectoderm to develop into neural plate (the primordium of CNS).It serves as the basis for development of axial skeleton. The notochord is an intricate structure around which veebral column is formed and indicates future site of veebral bodies. However, the notochord does not give rise to veebral column, after development of veebral bodies, the notochord degenerates and disappears, but pas of it persist as the nucleus pulposus of interveebral disc.
Defines axis of embryo
Serves as primary inductor
Derived from hypoblast
Remains as nucleus pulposus
