Final answer:
The olfactory epithelium contains olfactory receptor cells and basal cells. Olfactory receptor cells have specialized cilia that trap odorant molecules and each cell has only one type of receptor for specific odorants. Basal cells continuously produce new olfactory receptor cells.
Step-by-step explanation:
The olfactory epithelium and olfactory bulb are involved in the sense of smell. The olfactory epithelium contains two main types of cells: olfactory receptor cells and basal cells. Olfactory receptor cells have specialized cilia that trap odorant molecules, and each cell has only one type of receptor specialized to detect specific odorants. Basal cells are responsible for the continuous production of new olfactory receptor cells.
