Document Summary
Cell-to-cell adhesions: plasma membranes also participate in cell-to-cell adhesion. Cells are held together by three different means: cell adhesion molecules (cams) Allow cells to adhere or communicate, they are membrane proteins. Cadherin molecule those: the extracellular matrix (ecm) They are outside of the cell (extracellular: specialized cell junctions. The space in between the cells is called the interstitial fluid. Because this is how nutrients diffuse between cells. The molecules go under the interstitial fluid and connects to the cell. The ecm is an intricate meshwork of fibrous proteins embedded in a watery, gellike substance (a. k. a. interstitial fluid) composed of complex carbohydrates. Provides a pathway for diffusion of nutrients, wastes, and other water-soluble traffic between the blood and tissue cells. The three major types of protein fibers woven through the gel are: collagen: forms cable-like fibers tensile strength (most abundant protein in the body! They form cable like fibers and strengthens tissues.
