We just learned about the Olfactory Receptor.
Another part of the nose is the Olfactory Receptor Neuron.
The word "olfactory" means something to do with the sense of smell.
In Latin the word olere later turned into the English word odor, so olfactory means something like the smells factory.
The Olfactory Receptor we already learned about is where smells come in and get turned into messages for the brain.
The Olfactory Receptor Neurons are what take those messages from the Receptors and pass them on to the brain to understand what smells you are smelling.
