Which sense is associated with olfactory receptors?

• A. Sight
• B. Hearing
• C. Taste
• D. Smell

Answer: (D)

Olfactory receptors are specialized neurons in the nasal cavity that detect fragrant molecules in the air. When these odor molecules bind to the receptors, they generate nerve signals that travel to the brain regions responsible for processing smells, so the sense tied to these receptors is smell. Sight uses photoreceptors in the retina to detect light, and hearing uses hair cells in the inner ear to detect sound vibrations, while taste relies on taste receptor cells in taste buds to detect dissolved chemicals.
