The thin extracellular layer consisting of the basal and reticular lamina that anchors epithelial cells to underlying connective tissues is called what?

The thin extracellular layer that anchors epithelial cells to underlying connective tissues is called the basement membrane. It consists of two components: the basal lamina and the reticular lamina. The basal lamina is produced by the epithelial cells, while the reticular lamina is formed by connective tissue cells. This structure provides support, filtration, and a barrier function between tissues.
