Question

Which cells of our nasal cavities are responsible for detecting various odours?

• A. Photoreceptor cells
• B. Gustatory receptor cells
• C. Olfactory receptor cells
• D. Auditory receptor cells

Answer 1

The correct option is C Olfactory receptor cells

Olfactory receptor cells which are located at the back of our nasal cavities help in detecting various odours. The odour molecules travels through the nasal cavity and reaches the olfactory epithelium. It contains the olfactory receptors. The odorants latch onto the receptors surrounded by a layer of mucous. These receptors collectively activate the olfactory nerve which carries the nerve impulses to the brain for further interpretation.
