  2. Lamina propria - Wikipedia

    en.wikipedia.org/wiki/Lamina_propria

    The lamina propria is a thin layer of loose (areolar) connective tissue, which lies beneath the epithelium, and together with the epithelium and basement membrane constitutes the mucosa. As its Latin name indicates, it is a characteristic component of the mucosa, or the mucosa's "own special layer."

  3. Gastrointestinal wall - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_wall

    The lamina propria, a layer of connective tissue within the mucosa. The muscularis mucosae , a thin layer of smooth muscle . The epithelium, the most exposed part of the mucosa, is a glandular epithelium with many goblet cells .

  4. Tissue membrane - Wikipedia

    en.wikipedia.org/wiki/Tissue_membrane

    The underlying connective tissue, called the lamina propria (literally “own layer”), help support the fragile epithelial layer. A serous membrane is an epithelial membrane composed of mesodermally derived epithelium called the mesothelium that is supported by connective tissue. [2]

  5. Gastric mucosa - Wikipedia

    en.wikipedia.org/wiki/Gastric_mucosa

    In humans, it is about one mm thick, and its surface is smooth, soft, and velvety. It consists of simple secretory columnar epithelium, an underlying supportive layer of loose connective tissue called the lamina propria, and the muscularis mucosae, a thin layer of muscle that separates the mucosa from the underlying submucosa.

  6. Basement membrane - Wikipedia

    en.wikipedia.org/wiki/Basement_membrane

    The most notable examples of basement membranes is the glomerular basement membrane of the kidney, by the fusion of the basal lamina from the endothelium of glomerular capillaries and the podocyte basal lamina, [9] and between lung alveoli and pulmonary capillaries, by the fusion of the basal lamina of the lung alveoli and of the basal lamina ...

  7. Lamina (anatomy) - Wikipedia

    en.wikipedia.org/wiki/Lamina_(anatomy)

    The lamina propria: a connective tissue layer under the epithelium of an organ. [5] The nuclear lamina: a dense fiber network inside the nucleus of cells. [6] The lamina affixa: a layer of epithelium growing on the surface of the thalamus. The lamina of Drosophila is the most peripheral neuropil of the insect visual system.

  8. Gastrointestinal tract - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_tract

    Lamina propria – a layer of connective tissue. Unusually cellular compared to most connective tissue; Muscularis mucosae – a thin layer of smooth muscle that aids the passing of material and enhances the interaction between the epithelial layer and the contents of the lumen by agitation and peristalsis

  9. Gut-associated lymphoid tissue - Wikipedia

    en.wikipedia.org/wiki/Gut-associated_lymphoid_tissue

    Plasma B cells residing at lamina propria produce high levels of specific secretory IgA (sIgA) antibodies. These IgA are secreted into the lumen of the gut through the epithelial layer by transcytosis. Firstly epithelial cell binds a dimer of IgA via polymeric Ig receptor at the basolateral side and transports it in a vesicle into the luminal ...
