Quizplus · Accepted Answer

The correct pathway for olfactory information flowing from the nasal cavity to the brain is mucus, olfactory cilia, and then glomeruli. The mucus in the nasal cavity serves to capture odorant molecules, which then bind to olfactory receptor cells. These cells have cilia (not microvilli) that project from them into the mucus layer. The cilia contain receptors that bind to specific odorant molecules, sending signals to the glomeruli in the olfactory bulb. The glomeruli are clusters of cells that relay the information to the brain for further processing.
