Which of the following statements is incorrect regarding differences between epithelial and mesenchymal cells? Epithelial cells have adherens junctions and mesenchymal cells do not Mesenchymal cells are able to invade the basal lamina, epithelial cells can not Both cell types have clearly defined basal and apical polarity Only mesenchymal cells have front-end/back-end polarity
Which of the following is true regarding the permeability of the cytoplasmic membrane? Nothing can diffuse across the membrane All molecules can freely diffuse across it Only non-polar molecules can diffuse across the membrane It is generally impermeable to ions, polar molecules
A white blood cell travels through blood vessels along with red blood cells. A signal from the inside the tissue results in the white blood cell stopping, attaching to the vessel surface, and moving in between adjacent cells that line the blood vessel wall to enter the underlying tissue. Which structure is required for the cell to stop moving? cellulose O integrins O keratin O kinesin
Which of the following statements related to intercellular junctions is false? Cadherins are important cell-cell adhesion proteins. A cadherin-mediated junction involves many cadherin molecules to achieve strong adhesion. The cytoplasmic domain of cadherins interacts with actin or intermediate filament cytoskeleton through adaptor proteins. Because tight junctions seal the membrane of adjacent epithelial cells, transmembrane proteins in the apical portion of the plasma membrane cannot move to the basal lateral domain or vice versa. Proteins can diffuse through an open gap junction.
Which of the followings is not true about the function of the Tight Junctions? (LO- K8) They hold the cells together They act as a barrier They help maintain cell polarity They prevent lateral diffusion of proteins, ions, molecules They play an important role in maintaining the blood brain barrier They connect the adjacent cells intercellularly to the intermediate cytoskeletal filaments
What makes up a stratified epithelium? a single layer of cells of variable height squamous cells overlying cuboidal cells alternating layers of thick and thin cells multiple layers of cells, stacked from the basolateral side to the apical side a tight layer of square cells attached to a basement membrane
all the following statements which relate to apical surface modifications(brush border) of epithelial cells are true except. * these are anchored in a dense mat of microfilaments in the apical cytoplasm called the terminal, lateral web. The apical surface of cells in intestine is usually covered with microvilli. the microfilaments can contract, By interacting with cytoplasmic myosin, then caused the shortening of the microvilli. cores of microvilli are composed of parallel actin microfilaments.
Which of the followings is not a possible component of extracellular matrix? (LO-K8) Collagen Tubulin Glycosaminoglycans Elastin
Anchoring junctions are important in distributing of mechanical stress and maintains the integrity of epithelial cell layer
A white blood cell travels through blood vessels along with red blood cells. A signal from the inside the tissue results in the white blood cell stopping, attaching to the vessel surface, and moving in between adjacent cells that line the blood vessel wall to enter the underlying tissue. What connections would have to be broken for the white blood cell to do this? Select all that apply. tight junctions adherens junctions basal lamina gap junctions
