Why are adherins junctions so rigid?
Which type(s) of cell junctions contain actin filaments? Which contain(s)intermediate filaments? Which contain(s) integrins? Which contain(s) cadherins?
Match the following to their proper description (answers may be used more than once). Gap junctions Adhering junctions Desmosomes Hemidesmosomes Tight junctions Tight junctions Tight junctions Connexons Connexons Zonulae adherens Cadherins Desmosomes Are also known as “zonulae adherens”. Are also known as “zonulae occludens”. Are calcium ion-dependent glycoproteins that mediate adhesion in adhering junctions. Are hexameric complexes formed by connexin proteins. Bind the cells to the basal lamina. Contain a central hydrophilic pore and occur in gap junctions. Contain protein filaments. Encircle the cell and provide firm connections with neighboring cells. Form seals that prevent the flow materials between adjacent epithelial cells. Form thin bands that completely encircle the cell. Permit the rapid exchange of materials between adjacent cells. Provide firm adhesion between cells via protein filaments that are coupled to intracellular filaments via a protein plaques.
