Top explanations for GAP Junctions
Cell Interactions — Cell Biology: Organelle Structure and Function▶ 14:43Okay, we've established how cells anchor themselves securely with desmosomes and how they seal off compartments with tight junctionsNow we move to what is an absolute necessity of multicellular life, gap junctions in animalsThese structures are not about separation or holding things togetherIntegrating Cells into Tissues — Molecular Cell Biology▶ 13:27They prevent fluid and molecules from diffusing between cellsAnd gap junctions are the communicators, opening a direct bridge between the cytosols of neighboring cells for rapid exchangeAnd it's the anchoring junctions, particularly the desmosomes and hemidismomes, that allow tissues like our skin to withstand so much forceER, Golgi Complex & Lysosomes Overview — Karp's Cell and Molecular Biology▶ 37:00Now let's talk about opening channels for direct, rapid communicationWe'll start with gap junctions, the animal pipelineGap junctions are sites where the plasma membranes of adjacent cells come incredibly close, just 3 nanometers apart
