For which of the following apply: the extracellular space is eliminated here near the surface between two cells. A) Zonula adherens B)Zonula occluded C) Desmosome D) Gap junction E) Hemidesmosome
Integrins are important in cell crawling because they anchor the leading edge of the cell to the surface it is moving over they are receptors for diffusible chemical ligands that determine the direction the cell will move in they cross-link actin filaments to microtubules and intermediate filaments of the cytoskeleton they serve as nucleating sites for polymerization of new actin filaments
Cell motility has been described as being like the motion of tank treads. At the leading edge, actin filaments form rapidly into bundles and networks that make protrusions and move the cell forward. At the rear, cell adhesions are broken and the tail end of the cell is brought forward. What provides the traction for moving cells? How does cell-body translocation happen? How are cell adhesions released as cells move forward?
A cell junction is connecting the cell's cytoskeleton to the basement membrane. This is a ______ cell junction which uses the ____ adhesion molecule. desmisome ; integrin desmisome ; cadherin hemi-desmisome ; integrin hemi-desmisome ; cadherin
Which of the following statements applies to all three major classes of cytoskeletal polymers (microtubules, actin filaments and intermediate filaments)?

The difference between a gap junction and plasmodesmata is… Select one: a. Gap junctions are formed by microfilaments while plasmodesmata are formed by membrane b. Gap junctions are anchoring junctions while plasmodesmata are protein junctions. c. Gap junctions are formed by proteins making pores between two animal cells while plasmodesmata are formed due to incomplete cell division of membranes from adjoining plant cells.
