GENERAL HISTOLOGY

Detailed explanation-1: -Communicating junctions, or gap junctions allow for direct chemical communication between adjacent cellular cytoplasm through diffusion without contact with the extracellular fluid.

Detailed explanation-2: -Gap junctions are involved in cellular communication-not just in epithelial tissue, but in other tissue types as well. Gap junctions are specialized connections that form a narrow pore between adjacent cells. These pores permit small molecules and ions to move from one cell to another.

Detailed explanation-3: -Gap junctions are clusters of intercellular channels facilitating a direct connection between the cytoplasm of two neighbouring cells to mediate intercellular communication. These channels are formed by channel-forming proteins that are densely packed into spatial microdomains of the plasma membrane.

Detailed explanation-4: -Gap junctions are aggregates of intercellular channels that permit direct cell–cell transfer of ions and small molecules. Initially described as low-resistance ion pathways joining excitable cells (nerve and muscle), gap junctions are found joining virtually all cells in solid tissues.

Detailed explanation-5: -Gap junctions are also called communicating junctions, macula communicans, or nexuses. These are connections that allow for the direct passage of molecules between two cells.
