Olfactory receptors in the nasal cavity's mucus dissolve odorants, triggering nerve impulses that are sent to the brain via the olfactory bulb, with the combination of activated receptors determining the perceived scent.

| Front | olfactory receptors |
|---|---|
| Back | embedded in olfactory epithelium at back of nasal cavity; lined with mucus to dissolve odorants; binding of odorant to chemoreceptor triggers nerve impulse, transferred via olfactory bulb to brain; combination of activated olfactory receptors determines the scent |
