Question

what are the 4 events that occur when you smell apple pie

Answer 1

When you smell an apple pie, the first event that occurs is that the fumes enter your nasal cavity through inhaling. Your nasal cavity is lined witholfactoryepithelium which are the cells involved in the process of the smelling.What happens then is that thesmell receptorsfound within the olfactory epithelium bind with the odors of the molecules and then send a message stimulatingthe brain. This message is sent through theolfactory nerve.Now, the brain needs to distinguish the odor it received. The responsible part to do this istheolfactory bulbthat is located in the fore brain.
