 Adhering junctions: These act like cement to keep neighbouring cells together. These are of three types
      (a). Zonula adherens: These are dense plaque-like structure towards the cytoplasmic side of each plasma membrane from which fine microfilaments are extended into the cytoplasm. 
      (b). Desmosomes: These are also plaque-like thicker and stronger junctions with microfilaments of keratin protein. These microfilaments are called tonofibrils. This anchor the cells.
     (c). Hemidesmosome: These are similar to desmosomes, but the thickening of the cell membrane is seen on one side only. These join epithelial cells to the basal lamina.
