Tight junction • 2. Adherens junction • 3. Desmosome • 4. Hemidesrnosome • 5. Gap junction • 1. Tight junction • • Web-like strips of proteins fuse together adjacent plasma membranes. • • Tight junctions prevent the transport of the contents of organs such as the intestines, urinary bladder, and stomach into the blood or surrounding tissues. • 2. Adherens junction • • Anchored to a dense plaque of proteins inside the cell are transmembrane proteins that connect adjacent cells together. • • Additionally, microfilaments extend from the plaque into the cytosol. • Adhesion belts help resist separation of epithelial tissues. • #HomeworkClinic
