Read the following statements regarding the epithelial tissue that lines the inner surface of hollow organs like bronchioles and fallopian tubes. Choose the incorrect statement.

Options

  1. AGap junctions in this tissue primarily help to stop substances from leaking across the tissue.
  2. BThe cells constituting this tissue are modified columnar or cuboidal cells.
  3. CIts main function is to move particles or mucus in a specific direction over the epithelium.
  4. DAdhering junctions in this tissue perform cementing to keep neighbouring cells together.

Correct answer

A. Gap junctions in this tissue primarily help to stop substances from leaking across the tissue.

Step-by-step solution

The tissue present in the inner surface of hollow organs like bronchioles and fallopian tubes is ciliated epithelium. Ciliated epithelium consists of modified columnar or cuboidal cells that bear cilia on their free surface. Their main function is to move particles or mucus in a specific direction over the epithelium. In epithelial tissues, tight junctions help to stop substances from leaking across a tissue, whereas gap junctions facilitate communication between cells by connecting the cytoplasm of adjoining cells
