NEET PG DENTAL EXAM

Detailed explanation-1: -The basal lamina is a layer of extracellular matrix secreted by the epithelial cells, on which the epithelium sits. It is often incorrectly referred to as the basement membrane, though it does constitute a portion of the basement membrane.

Detailed explanation-2: -The basal lamina constitutes a thin extracellular matrix, which is located between the connective tissue and the basolateral side of a cell layer. This cellular layer can consist of either endothelial or epithelial cells, and those cell types secrete the different molecular components of the basal lamina.

Detailed explanation-3: -The key difference between basal lamina and basement membrane is that basal lamina is composed of two layers while basement membrane is composed of three layers. Epithelial cells are tightly bound into sheets called epithelia. The extracellular matrix is small and thin and underlies the epithelium.
