cell junctions

A variety of types of intercellular connections which may also allow cells to communicate with each other. Tight junctions (e.g. between epithelial cells) connect cells together to form a fluid-tight seal. Anchoring junctions, in which the cell’s cytoskeleton joins cells to one another, are found in tissues that are subject to friction and stretching (e.g. muscle tissue in the heart). In the third type, gap junctions, the adjacent cell membranes come extremely close to each other but do not actually touch. At gap junctions, pores in the cell membranes allow the transfer of material from cell to cell.
