apical plasma membrane
The term used for the cell membrane on the apical (inner or upper) surface of transporting epithelial cells. This region of the cell membrane is separated, in vertebrates, from the baso-lateral membrane by a ring of tight junctions that prevents free mixing of membrane proteins from these two domains.
