It is typically about 40-50 nanometres thick (with exceptions such as the basal laminae that compose the 100-200 nanometre thick glomerular basement membrane). Irregularities in the connective tissue surface, such as papillae found in the tongue, increase the area of contact of the lamina propria and the epithelium. the layer of connective tissue beneath the epithelial linking of internal organs. 4 synonyms for lamina: membrane, sheath, sheathing, skin. [1], The connective tissue of the lamina propria is loose and rich in cells. [3], The lamina propria is a loose connective tissue, hence it is not as fibrous as the underlying connective tissue of the submucosa. The lamina propria forms the connective tissue core of the villi and surrounds the crypt epithelium. The basal lamina is a layer on which epithelium sits and which is secreted by the epithelial cells.

Afferent and efferent nerve endings can be found in the lamina propria as well. 2. vertebral lamina . Basal Lamina Reticular Lamina Most epithelial cells are separated from the connective tissue by a sheet of extracellular material called Basement Membrane. The basal lamina consists of ECM components such as collagen type IV, fibronectin, and laminin, and it functions to stabilize the epithelium and act as a barrier to migratory cells (Erickson, 1987). The crypt and villus epithelial cells and the lamina propria are separated by a distinct basement membrane composed of an ultrastructurally apparent basal lamina and a deeper network of collagenous fibers. Thus, the term mucosa or mucous membrane refers to the combination of the epithelium and the lamina propria. It is formed by the association of two layers : Basal lamina and reticular lamina.
