4 types of tissue: epithelial tissue covers body surfaces and lines hollow organs, body cavities, and ducts; it also forms glands. This tissue allows the body to interact with both its internal and external environments: connective tissue protects and supports the body and its organs. Various types of connective tissues bind organs together, store energy reserves as fat, and help provide the body with immunity to disease-causing organisms: muscular tissue is composed of cells specialized for contraction and generation of force. Biopsy removal of living tissue for examination. Cell junctions are contact points between the plasma membranes of tissue cells. Cells are held together to form tissues, epithelial cells and some muscle and nerve cells are tightly joined, cell junctions are contact points between the plasma membranes of tissue cells. Tight junctions - consist of web like strains of transmembrane proteins that fuse together the outer surfaces of adjacent plasma membranes to seal off passageways between adjacent cells.
