A person has difficulty detecting smell but has no problem seeing or hearing. Which conclusion is most suitable?
Answer and explanation
Correct answer: The olfactory receptors or their associated neural pathway may be affected
Smell is detected by specialised olfactory receptors in the nasal lining, and the information travels through an olfactory neural pathway to the brain. Since vision and hearing remain normal, the problem is more likely restricted to the smell receptors or their pathway rather than all sensory systems. Thus option A is the best conclusion. Photoreceptor damage would affect vision, while the medulla and pancreas do not specifically explain isolated loss of smell.
