The Olfactory SystemThe Olfactory System
How Does It Work?
Sense of Smell
Detection of chemicals floating in the air.
Chemical molcules enter the nose and dissolve in mucous within a membrane called Olfactory Epithelium
Humans~Olfactory epithelium is 7 cm up from the nostrils
![Page 7: Anatomy of the Nose Amanda Morgan, MS, OTR/L Weatherly Landry, OTA/S 2/1/2010.](https://reader035.fdocuments.net/reader035/viewer/2022062618/551441a1550346494e8b498e/html5/thumbnails/7.jpg)
Do nose hairs have a purpose?
Do nose hairs have a purpose?
Hair cells or cilli ~olfactory receptors that respond to particular chemicals.
Humans ~ 40 million olfactory receptors
German Sheherd dog~ 2 billion olfactory receptors
Hair cells, or cilia or olfacotry receptors react and send information to the olfactory bulb.
Old factory sends message to the brain (limbic system).emotional behavior, memory
Smell can bring up memories

More Olfactory System
Fibers and cells in the Olfactory Epithelium then carry the message to the Olfactory Bulb.
The bulb then sends the messages to the brain, including the Temporal Lobe.

The Temporal Lobe
Your Temporal Lobe is responsible for recognizing memories.
That’s why smell is connected to memory!
Where are your Temporal Lobes?
