Cell junctions - sites on the cell membrane where cells attach to neighbouring cells. There are three main types. 1. adhering junctions, which anchor cells to each other to resist separation. They may form a belt of adhesions between cells (as between muscle cells) or spot attachments like desmosomes which hold epithelial cells together. 2. tight junctions have no space between the membranes and allow no leakage between cells. They are found between cells of a secreting glands and between endothelial cells of blood vessels to prevent fluid leaking out. 3. gap junctions are channels which allow transfer of small molecules like ions, sugars and amino acids, between cells.
