Summary Introduction
Introduction: The intercellular bridge is also called cell junction and it is a structure that occurs inside the tissues of certain multicellular organisms. For example, in animals. A multiprotein complex is present in the cell junction that gives contact between a cell or neighbouring cells and extracellular matrix. The examples of cell junction are gap junction or adhering junction, tight junction, and plasmodesmata of plants.
