In some kinds of cells, the cell membrane represents differentiations which are essential for the particular functions of the cells. The main differentiations are the microvilli and the structures for reinforcement of adhesion or union among cells (that is, cell junctions). Microvilli are multiple exterior projections of the membrane similar to glove fingers. This differentiation is found in cells of tissues where it is beneficial to enlarge the size of the surface area in contact with the external, for illustration, in the enteric (that is, intestinal) epithelium for the absorption of nutrients.

Membrane differentiations for the reinforcement of adhesion among cells take place mostly in epithelial tissues where the requirement for coverage and impermeability needs cells to be “glued” to neighboring cells. Such differentiations can be desmosomes, interdigitations, tight junctions (or zonula occludens), zonula adherens (adherens junctions) and the gap junctions.
