Gap Junction: Definition, Function, Structure - Biology Dictionary
网页2019年10月4日 · 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 junction - Wikipedia
网页Gap junctions are membrane channels between adjacent cells that allow the direct exchange of cytoplasmic substances. [1] Substances exchanged include small molecules, substrates, and metabolites. [1]
Gap Junctions - Definition, Structure, Functions, and Diagram
网页2023年8月29日 · Gap junctions allow direct communication between neighboring cells. It allows them to exchange various substances, including ions, metabolites, and signaling molecules. This direct transfer of substances facilitates coordinated and synchronized cellular activities within tissues.
