Multiple Choice

The cells responsible for separating epithelial cells from the basement membrane are called?

The main idea is that the epithelium sits on the basement membrane, and a specialized, contractile cell type lies between the epithelial layer and that basement membrane. These myoepithelial cells surround secretory units and ducts and, by contracting, help squeeze secretions out into the ducts. They’re distinct from other cell types: fibroblasts reside in the connective tissue stroma, endothelial cells line blood vessels, and chondrocytes are in cartilage. So the cells that separate epithelial cells from the basement membrane are myoepithelial cells.
