(noun)

Composed of cells derived from the mesoderm, this provides signals to the surrounding tissue during development.

Examples of notochord in the following topics:

  • Bilaminar Embryonic Disc Development

    • As gastrulation progresses, the embryonic disc becomes trilaminar and the notochord is formed.
    • Through the through the process of neurulation, the notochord induces the formation of the notochord in the embryonic disc.
  • Neurulation

    • Following gastrulation, the neurulation process develops the neural tube in the ectoderm, above the notochord of the mesoderm.
    • After gastrulation, the notochord—a flexible, rod-shaped body that runs along the back of the embryo—is formed from the mesoderm.
    • During the third week of gestation the notochord sends signals to the overlying ectoderm, inducing it to become neuroectoderm.
  • Gastrulation

    • The somites form muscle, the cartilage of the ribs and vertebrae, the dermis, the notochord, blood and blood vessels, bone, and connective tissue.
  • Embryonic Development of the Brain

    • After gastrulation, the notochord—a flexible, rod-shaped body that runs along the back of the embryo—has been formed from the mesoderm.
    • During the third week of gestation, the notochord sends signals to the overlying ectoderm, inducing it to become neuroectoderm.
  • Embryonic Development

    • These cell types are specified by the secretion of Shh from the notochord (located ventrally to the neural tube), and later from the floor plate cells.
