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...

Lecture 27 - Cell Junctions Questions And Answers 1 / 2 1. Cell junctions (intercellular bridges) multiprotein complexes that provide contact or adhesion between neighboring cells and the extracellular matrix. They hold animal cells together and enable communication between cells. 2. Cell Junction types gap junctions, tight junctions, anchoring junctions 3. gap junctions communication between cells. Made of 6 identical connexin subunits. A single connexin has 4 transmembrane protei...
