Oct 4, 2019 · Gap junctions are a type of cell junction in which adjacent cells are connected through protein channels. These channels connect the cytoplasm of each cell and allow molecules, ions, and electrical signals to pass between them.

Gap junctions are membrane channels between adjacent cells that allow the direct exchange of cytoplasmic substances, such small molecules, substrates, and metabolites. [1]

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.

Aug 29, 2023 · Gap junctions are a group of intercellular channels that establish direct connections between neighboring cells in animals. They are also known as communicating junctions, macula communicans, or nexuses.

These junctions allow communication between adjacent cells via the passage of small molecules directly from the cytoplasm of one cell to that of another. Molecules that can pass between cells coupled by gap junctions include inorganic salts, sugars, amino acids, nucleotides, and vitamins but not large molecules such as proteins or nucleic acids.

Jan 17, 2023 · 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. Gap junctions consist of a number of transmembrane channels called pores that are found in a closely packed arrangement.

Apr 26, 2023 · Gap junctions are intercellular channels that enable direct communication and the exchange of ions, tiny molecules, and electrical impulses between neighboring cells. Here are some crucial aspects to consider when learning about gap junctions:
