Question
What do you understand by special junctions between cells? Which type of special junction are found in epithelial tissues?

Answer

All cells are held together with intercellular material. These materials form junctions between cells. There are three types of cell junctions found in epithelial tissue:
  1. Tight Junctions: These junctions help in stopping leakage of substances across a tissue.
  2. Adhering Junctions: These junctions keep neighbouring cells together.
  3. Gap Junctions: These junctions connect cytoplasm of adhering cells, and facilitate exchange of materials.
