Quizplus · Accepted Answer

Odorants first excite neurons in the olfactory epithelium, which is located in the nasal cavity. These excited neurons then send signals to the olfactory bulb, located at the base of the brain, which further processes and analyzes the information from the odorants. Choice A (buds) and B (pores) are not accurate because the olfactory epithelium is made up of specialized cells called olfactory receptor neurons, not taste buds, and does not have pores.
