WebVoiceover: In this video we're gonna talk a little bit about cell junctions. Cell junctions are basically things that connect cells to other cells. And they often occur in epithelial tissue. We're gonna talk about three major types of cell junctions today. The first, tight junctions, the second desmosomes, and the third, gap junctions. WebIn vertebrates, there are three major types of cell junction: . Adherens junctions, desmosomes and hemidesmosomes (anchoring junctions); Gap junctions (communicating junction); Tight junctions (occluding junctions); Invertebrates have several other types of specific junctions, for example septate junctions or the C. elegans apical junction.
