Document Summary

Define the general structure and function of the extracellular matrix. Describe the function and structure of basement membranes. Describe the structures of the components of the extracellular matrix (collagen, fibronectin, laminin, proteoglycans) and differentiate between them. Compare the different mechanisms through which cells adhere to a non cellular surface. Describe the membrane proteins involved in the adhesion of cells to non cellular surfaces. Describe the structures and functions of the different cell junctions. Describe the membrane proteins involved in cell-cell adhesion. The extracellular space is all space and any element outside of the plasma membrane. Many portions of integral membrane proteins and membrane lipids project into the extracellular space. The glycocalyx is a cell coat formed from carbohydrate projections and acts to: The extracellular matrix (ecm) is an organized network of extracellular materials that provides physical and biochemical signals that regulate the shape and activities of the cell.
