  2. Lamellar bodies - Wikipedia

    en.wikipedia.org/wiki/Lamellar_bodies

    Red arrows indicate secreted lamellar bodies, and green arrows indicate lamellar bodies in the cytoplasm. Scale bar = 200 nm. In cell biology, lamellar bodies (otherwise known as lamellar granules, membrane-coating granules (MCGs), keratinosomes or Odland bodies) are secretory organelles found in type II alveolar cells in the lungs, and in keratinocytes in the skin.

  3. Lamella (cell biology) - Wikipedia

    en.wikipedia.org/wiki/Lamella_(cell_biology)

    A lamella (pl.: lamellae) in biology refers to a thin layer, membrane or plate of tissue. [1] This is a very broad definition, and can refer to many different structures. Any thin layer of organic tissue can be called a lamella and there is a wide array of functions an individual layer can serve.

  4. Corneocyte - Wikipedia

    en.wikipedia.org/wiki/Corneocyte

    The lipids ultimately form the lamellar lipid bilayer that surrounds corneocytes and also contributes to the permeability barrier homeostasis of the stratum corneum. [12] The homeostasis function is regulated by the calcium gradient in the epidermis. [17] Usually the calcium level is very low in stratum corneum, but high in stratum granulosum.

  5. Pacinian corpuscle - Wikipedia

    en.wikipedia.org/wiki/Pacinian_corpuscle

    The Pacinian corpuscle (also lamellar corpuscle, or Vater-Pacini corpuscle) [1] is a low-threshold mechanoreceptor responsive to vibration or pressure, found in the skin and other internal organs. [2] In the skin it is one of the four main types of cutaneous receptors.

    Section parallel to the surface from the body of the femur. X 100. a, Haversian canals ; b, lacunae seen from the side; c, others seen from the surface in lamella , which are cut horizontally. Nucleated bone cells and their processes, contained in the bone lacunae and their canaliculi respectively.

  7. Lamella (surface anatomy) - Wikipedia

    en.wikipedia.org/wiki/Lamella_(surface_anatomy)

    Lamellae on a gecko's foot. In surface anatomy, a lamella is a thin plate-like structure, often one amongst many lamellae very close to one another, with open space between.

  8. Annulate lamella - Wikipedia

    en.wikipedia.org/wiki/Annulate_lamella

    They are characteristic of actively growing cells, including many functions in genetic information transfer and storage. They are probably formed from the nuclear envelope. [3] [4] Similar membranes are found in both the cytoplasm and nucleoplasm. In the nucleoplasm, they are small, irregular, and short-lived.

  9. Pulmonary alveolus - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_alveolus

    Type II cells (granulous pneumocytes) in the alveolar wall contain secretory organelles known as lamellar bodies or lamellar granules, that fuse with the cell membranes and secrete pulmonary surfactant. This surfactant is a film of fatty substances, a group of phospholipids that reduce alveolar surface tension. The phospholipids are stored in ...
