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. WebDesmosomes are intracellular adhesion structures that are critical for cell–cell attachment in the epithelial and myocardial tissues and in other tissues (16).
