  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. Goblet cells secrete mucus, which lubricates the passage of food along and protects the intestinal wall from digestive ...

  4. Vocal cords - Wikipedia

    en.wikipedia.org/wiki/Vocal_cords

    Since the basal lamina secures the epithelium to the superficial layer of the lamina propria with anchoring fibers, this is a common site for injury. If a person has a phonotrauma or habitual vocal hyperfunction, also known as pressed phonation, the proteins in the basal lamina can shear, causing vocal fold injury, usually seen as nodules or ...

  5. Histology of the vocal cords - Wikipedia

    en.wikipedia.org/wiki/Histology_of_the_vocal_cords

    The cover is composed of the epithelium (mucosa), basal lamina (or basement membrane zone), and the superficial layer of the lamina propria. The transition is composed of the intermediate and deep layers of the lamina propria. The body is composed of the thyroarytenoid muscle. This layered structure of tissues is very important for vibration of ...

  6. Basement membrane - Wikipedia

    en.wikipedia.org/wiki/Basement_membrane

    The primary function of the basement membrane is to anchor down the epithelium to its loose connective tissue (the dermis or lamina propria) underneath.This is achieved by cell-matrix adhesions through substrate adhesion molecules (SAMs).

  7. Gut-associated lymphoid tissue - Wikipedia

    en.wikipedia.org/wiki/Gut-associated_lymphoid_tissue

    Its main function is to induce immune reaction. 2.) diffuse GALT with single T and B cells, macrophages, eosinophiles, basophiles and mast cells, preferentially found in lamina propria. This part of GALT is made up from mature effector cells ready to perform their actions.

  8. Olfactory glands - Wikipedia

    en.wikipedia.org/wiki/Olfactory_glands

    Olfactory glands, also known as Bowman's glands, are a type of nasal gland situated in the part of the olfactory mucosa beneath the olfactory epithelium, that is the lamina propria, a connective tissue also containing fibroblasts, blood vessels and bundles of fine axons from the olfactory neurons.

  9. 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.
