Questions and Answers

What type of cells are found in the olfactory epithelium?

  • Olfactory receptor cells, interneurons, and astrocytes
  • Olfactory receptor cells, sustentacular cells, and Bowman's glands
  • Olfactory receptor cells, supporting cells, and basal cells (correct)
  • Olfactory receptor cells, ependymal cells, and goblet cells

    • What is the function of the Bowman's glands in the olfactory epithelium?

  • To detect and transmit olfactory signals to the olfactory bulb
  • To produce mucus that moistens the surface of the olfactory epithelium and dissolves odorants (correct)
  • To generate new olfactory receptor cells from basal cells
  • To provide structural support for the olfactory receptor cells

    • What is the role of the olfactory cilia in olfactory transduction?

  • The olfactory cilia are involved in the secretion of mucus by Bowman's glands.
  • The olfactory cilia are responsible for the movement of odorants through the nasal cavity.
  • The olfactory cilia provide structural support for the olfactory receptor cells.
  • The olfactory cilia are the sites of olfactory transduction, where odorants bind to and activate olfactory receptors. (correct)

    • What is the relationship between olfactory receptor cells and the olfactory bulb?

    <p>Olfactory receptor cells are part of the second-order neurons of the olfactory pathway, with their axons projecting through the cribriform plate to the olfactory bulb.</p> Signup and view all the answers

    What is the function of the basal cells in the olfactory epithelium?

    <p>Basal cells are undifferentiated stem cells that give rise to the olfactory receptor cells.</p> Signup and view all the answers

    What is the primary function of the supporting (sustentacular) cells in the olfactory epithelium?

    <p>Supporting cells provide structural support and insulation for the olfactory receptor cells.</p> Signup and view all the answers

    What is the role of the cribriform plate in the olfactory pathway?

    <p>The cribriform plate is the structure through which the axons of the olfactory receptor cells project to reach the olfactory bulb.</p> Signup and view all the answers

    What is the primary function of the olfactory receptor cells?

    <p>Olfactory receptor cells are the primary sensory neurons that detect and transduce olfactory stimuli.</p> Signup and view all the answers

    How do odorants interact with olfactory receptor cells to initiate olfactory transduction?

    <p>Odorants bind to and activate receptors on the olfactory cilia, which are the sites of olfactory transduction.</p> Signup and view all the answers
