A patient can detect the smell of freshly cooked food but cannot consciously identify its flavour after chewing. Which statement best explains this finding?
Correct answer: B. Smell contributes significantly to flavour perception during eating
- A. Taste receptors detect all flavour sensations independently of smell
- B. Smell contributes significantly to flavour perception during eating
- C. The optic nerve carries flavour signals from the tongue
- D. The vestibular apparatus identifies food chemicals
Explanation
Flavour perception combines taste sensations from the tongue with olfactory information from the nasal cavity. Blocking or losing smell can greatly reduce flavour identification even when basic taste reception remains present.

About Nervous System and Special Senses
The nervous system covers neurons, neuroglia, nerve impulses, synapses, reflex arcs, and the organization of the central and peripheral nervous systems. It also explains the autonomic divisions and the receptors and pathways for vision, hearing, balance, taste and smell, distinguishing sensory reception from conscious perception.
