Extracellular Matrix (ECM) - -relatively stable structural material that lies under epithelia & that surrounds connective tissue cells -can be divided into 2 structural components: fibers & amorphous ground substance Fibers - -an aggregate of fibrils -1-10 um diameter (largest) -can be divided into collagen & elastic -each is comprised of specific types of proteins -can assemble into bundles Fibrils - -an aggregate of filaments (filaments put together = fibrils) -20-500nm diameter -col...

What is the ECM? ANS Extracellular matrix a network of proteins and polysaccharide chains that are secreted by cells What are the two forms of the ECM? What are they each? ANS ECM of connective tissue= fibrous polymers like collagen Basal Lamina= flexible, thin mat of specialized ECM that underlies epithelial cell sheets and tubes What are the two ways that cells are attached in tissue? ANS either to the basal lamina or to the ECM and to each other What are the 4 main types of junct...
