  2. Notochord - Wikipedia

    en.wikipedia.org/wiki/Notochord

    Red: notochord; Magenta: axochord; Green: nerve chord; Blue: epidermis; Yellow: mesoderm. The notochord is an elastic, rod-like structure found in chordates. In chordate vertebrates the notochord is an embryonic structure that disintegrates, as the vertebrae develop, to become the nucleus pulposus in the intervertebral discs of the vertebral ...

  4. Lancelet - Wikipedia

    en.wikipedia.org/wiki/Lancelet

    The lancelet notochord, unlike the vertebrate spine, extends into the head. This gives the subphylum, Cephalochordata, its name ( κεφαλή , kephalē means 'head'). The fine structure of the notochord and the cellular basis of its adult growth are best known for the Bahamas lancelet, Asymmetron lucayanum [ 51 ]

  5. Neurulation - Wikipedia

    en.wikipedia.org/wiki/Neurulation

    The notochord plays an integral role in the development of the neural tube. Prior to neurulation, during the migration of epiblastic endoderm cells towards the hypoblastic endoderm, the notochordal process opens into an arch termed the notochordal plate and attaches overlying neuroepithelium of the neural plate. The notochordal plate then ...

  6. Stomochord - Wikipedia

    en.wikipedia.org/wiki/Stomochord

    In addition, gene expression studies have failed to provide any evidence for homology between the notochord and the stomochord, or between the notochord and any hemichordate structure. The Brachyury (T) gene, which is expressed in the ascidian and other chordates notochord, is not expressed in the stomochord, and collagen is absent. [2]

  8. Neurula - Wikipedia

    en.wikipedia.org/wiki/Neurula

    HNF-3 is needed for development of the notochord and node. [14] The gene Apolipoprotein B, which is involved in transporting and metabolizing fat soluble molecules in the blood, is expressed in the yolk sac and fetal liver. [6] Within the neurula in Xenopus laevis, development genes Xwnt-3 and Xwnt-4 are present. [15]

  9. Prechordal plate - Wikipedia

    en.wikipedia.org/wiki/Prechordal_plate

    In the 10 somite embryo, Carnegie No. 5074, the prechordal plate is continuous posteriorly with the notochord, and is made up of about 35-40 cells. The prechordal mesenchyme proliferates laterally over the junction of the dorsal aorta and first aortic arch on each side. Gilbert P.W., (1957) STAGE 11
