The plasmalemma at the free surface of a number of kinds of epithelia possesses a pelage of delicate branching filaments that are matted together to form a continuous coating. This layer is particularly well-developed in the cells lining the gastrointestinal tract. Magnification 21,000x. Transmission electron micrograph.
