Epithelial Tissue (Part 1)

In addition to covering all body surfaces, epithelial tissues line body cavities, line hollow organs, and are the most abundant tissue in glands. The functions of these cells are protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.

This quiz will teach you about the types, parts, and functions of epithelial tissues.

  • Question of

    Generally, the part of a cell or tissue facing open space.

    • Apical
    • Endothelium
    • Basal lamina
    • Basement membrane

    Correct Wrong

    Apical refers to the part of a cell or tissue facing open space.

  • Question of

    Extracellular matrix secreted by epithelial cells, on which the epithelium is situated.

    • Basal lamina
    • Endothelium
    • Goblet cells
    • Mesothelium

    Correct Wrong

    A mixture of glycoproteins and collagen, the basal lamina provides an attachment site for the epithelium.

  • Question of

    Comprised of the basal lamina and reticular lamina.

    • Basement membrane
    • Apical
    • Basal lamina
    • Endothelium

    Correct Wrong

    A basement membrane in epithelial tissue is a fibrous material that anchors the epithelial tissue to the underlying connective tissue; it is composed of the basal lamina and the reticular lamina. In addition to being a cell and tissue support, it is also a platform for complex signaling.

  • Question of

    This junction is a point of cell-to-cell contact that connects one cell to another in a tissue.

    • Cell junction
    • Tight junction
    • Gap junction
    • Goblet cells

    Correct Wrong

    A cell junction is a point of cell-to-cell contact in a tissue that connects one cell to another. Cell-to-cell junctions can be classified into three types: tight junctions, gap junctions, and anchoring junctions.

  • Question of

    A junction that has a general function to prevent leakage of transported solutes and water and seals pathway.

    • Tight junction
    • Cell junction
    • Gap junction
    • Endothelium

    Correct Wrong

    In general, tight junctions are multiprotein junctional complexes whose purpose is to prevent leakage of transported solutes and water and to seal the paracellular pathway.

  • Question of

    A junction that forms a passageway between the membranes to facilitate the movement of small molecules and ions.

    • Gap junction
    • Cell junction
    • Tight junction
    • Mesothelium

    Correct Wrong

    Gap junctions facilitate the movement of small molecules and ions between adjacent cells by creating an intercellular passageway between their membranes. They allow electrical and metabolic communication between adjacent cells, which coordinates functions within large groups of cells.

  • Question of

    A type of epithelium that is found in capillaries, alveoli, and glomeruli.

    • Simple squamous epithelium
    • Simple cuboidal epithelium
    • Transitional epithelium
    • Simple columnar epithelium

    Correct Wrong

    A simple squamous epithelium is made up of a single layer of flat cells in contact with the basal lamina (one of two layers of basement membrane). Simple squamous epithelia can be found in capillaries, alveoli, glomeruli, and other tissues where rapid diffusion is needed.

  • Question of

    An epithelial tissue that lines lymphatic and cardiovascular vessels.

    • Endothelium
    • Basement membrane
    • Mesothelium
    • Apical

    Correct Wrong

    Squamous endothelial cells lining the interior surface of vessels including blood vessels and lymphatic vessels make up the endothelium. Blood and lymph flow through the endothelium, which serves as an interface between the lumen and the rest of the vessel wall.

  • Question of

    Serous membrane surface layer consisting of a simple squamous epithelium.

    • Mesothelium
    • Endothelium
    • Apical
    • Goblet cells

    Correct Wrong

    The mesothelium is a squamous epithelium lining the body cavities and internal organs with serous membranes. Mesothelium provides a smooth and protective surface to the body cavities and internal organs.

  • Question of

    A type of epithelium that are observed in the lining of the kidney tubules and the ducts of glands.

    • Simple cuboidal epithelium
    • Pseudostratified columnar epithelium
    • Transitional epithelium
    • Stratified squamous epithelium

    Correct Wrong

    A simple cuboidal epithelium is one that is composed of a single layer of cuboidal (cube-like) cells. They have large, spherical, and central nuclei. A simple cuboidal epithelium cover the surface of the ovaries, the lining of the nephron, the walls of the kidney tubules, and parts of the eye and thyroid.
