  2. Simple columnar epithelium - Wikipedia

    en.wikipedia.org/wiki/Simple_columnar_epithelium

    The ciliated part of the simple columnar epithelium has tiny hairs which help move mucus and other substances up the respiratory tract. The shape of the simple columnar epithelium cells are tall and narrow giving a column like appearance. the apical surfaces of the tissue face the lumen of organs while the basal side faces the basement membrane ...

  3. Ependyma - Wikipedia

    en.wikipedia.org/wiki/Ependyma

    The ependyma is the thin neuroepithelial (simple columnar ciliated epithelium) lining of the ventricular system of the brain and the central canal of the spinal cord. [1] The ependyma is one of the four types of neuroglia in the central nervous system (CNS).

  5. Respiratory epithelium - Wikipedia

    en.wikipedia.org/wiki/Respiratory_epithelium

    The cells in the respiratory epithelium are of five main types: a) ciliated cells, b) goblet cells, c) brush cells, d) airway basal cells, and e) small granule cells (NDES) [6] Goblet cells become increasingly fewer further down the respiratory tree until they are absent in the terminal bronchioles; club cells take over their role to some extent here. [7]

  6. Epithelium - Wikipedia

    en.wikipedia.org/wiki/Epithelium

    There are three principal shapes of epithelial cell: squamous (scaly), columnar, and cuboidal. These can be arranged in a singular layer of cells as simple epithelium, either simple squamous, simple columnar, or simple cuboidal, or in layers of two or more cells deep as stratified (layered), or compound, either squamous, columnar or cuboidal ...

  7. Bronchiole - Wikipedia

    en.wikipedia.org/wiki/Bronchiole

    The epithelium of the bronchioles starts as a simple ciliated columnar epithelium and changes to simple ciliated cuboidal epithelium as the bronchioles decreases in size. The diameter of the bronchioles is often said to be less than 1 mm, though this value can range from 5 mm to 0.3 mm.

  8. Enterocyte - Wikipedia

    en.wikipedia.org/wiki/Enterocyte

    Enterocytes, or intestinal absorptive cells, are simple columnar epithelial cells which line the inner surface of the small and large intestines. A glycocalyx surface coat contains digestive enzymes. Microvilli on the apical surface increase its surface area.

  9. Basal cell - Wikipedia

    en.wikipedia.org/wiki/Basal_cell

    They reside in the mucosal layer of the respiratory epithelium, and generally remain dormant. However, when a functional epithelial cell becomes damaged, a basal cell is activated to differentiate into the appropriate cell type and replace the damaged cell.
