  2. Neuroepithelial cell - Wikipedia

    en.wikipedia.org/wiki/Neuroepithelial_cell

    Neuroepithelial cells of the ectoderm begin multiplying rapidly and fold in forming the neural plate, which invaginates during the fourth week of embryonic growth and forms the neural tube. [2] The formation of the neural tube polarizes the neuroepithelial cells by orienting the apical side of the cell to face inward, which later becomes the ...

  3. Neural tube - Wikipedia

    en.wikipedia.org/wiki/Neural_tube

    The neural tube develops in two ways: primary neurulation and secondary neurulation. Primary neurulation divides the ectoderm into three cell types: The internally located neural tube; The externally located epidermis; The neural crest cells, which develop in the region between the neural tube and epidermis but then migrate to new locations

  4. Neuroectoderm - Wikipedia

    en.wikipedia.org/wiki/Neuroectoderm

    Neuroectoderm (or neural ectoderm or neural tube epithelium) consists of cells derived from the ectoderm. Formation of the neuroectoderm is the first step in the development of the nervous system . [ 1 ]

  5. Ectoderm - Wikipedia

    en.wikipedia.org/wiki/Ectoderm

    In vertebrate embryos, the ectoderm can be divided into two parts: the dorsal surface ectoderm also known as the external ectoderm, and the neural plate, which invaginates to form the neural tube and neural crest. [4] The surface ectoderm gives rise to most epithelial tissues, and the neural plate gives rise to most neural tissues.

  6. Germ layer - Wikipedia

    en.wikipedia.org/wiki/Germ_layer

    It forms the epithelial lining of the whole of the digestive tract except part of the mouth and pharynx and the terminal part of the rectum (which are lined by involutions of the ectoderm). It also forms the lining cells of all the glands which open into the digestive tract, including those of the liver and pancreas; the epithelium of the ...

  7. Neural crest - Wikipedia

    en.wikipedia.org/wiki/Neural_crest

    The neural crest is a ridge-like structure that is formed transiently between the epidermal ectoderm and neural plate during vertebrate development. Neural crest cells originate from this structure through the epithelial-mesenchymal transition, and in turn give rise to a diverse cell lineage—including melanocytes, craniofacial cartilage and bone, smooth muscle, dentin, peripheral and enteric ...

  9. Organogenesis - Wikipedia

    en.wikipedia.org/wiki/Organogenesis

    This fold along the neural tube sets up the vertebrate central nervous system. The endoderm is the inner most germ layer of the embryo which gives rise to gastrointestinal and respiratory organs by forming epithelial linings and organs such as the liver, lungs, and pancreas. [5]
