9 Questions
What type of cells are found in the olfactory epithelium?
Olfactory receptor cells, supporting cells, and basal cells
What is the function of the Bowman's glands in the olfactory epithelium?
To produce mucus that moistens the surface of the olfactory epithelium and dissolves odorants
What is the role of the olfactory cilia in olfactory transduction?
The olfactory cilia are the sites of olfactory transduction, where odorants bind to and activate olfactory receptors.
What is the relationship between olfactory receptor cells and the olfactory bulb?
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.
What is the function of the basal cells in the olfactory epithelium?
Basal cells are undifferentiated stem cells that give rise to the olfactory receptor cells.
What is the primary function of the supporting (sustentacular) cells in the olfactory epithelium?
Supporting cells provide structural support and insulation for the olfactory receptor cells.
What is the role of the cribriform plate in the olfactory pathway?
The cribriform plate is the structure through which the axons of the olfactory receptor cells project to reach the olfactory bulb.
What is the primary function of the olfactory receptor cells?
Olfactory receptor cells are the primary sensory neurons that detect and transduce olfactory stimuli.
How do odorants interact with olfactory receptor cells to initiate olfactory transduction?
Odorants bind to and activate receptors on the olfactory cilia, which are the sites of olfactory transduction.
Test your knowledge on the generation and propagation of action potentials along olfactory nerve axons towards the olfactory bulb. Explore the mechanism behind activating olfactory nerves and the exquisite sensitivity of olfactory neurons to various odorants.
