Olfaction Flashcards
Where is air filtered in the nasal passage to smell?
Flows over the Turbinate Bones
Where are the cell bodies of olfactory receptors located?
The Olfactory Epithelium, which lines the skull.
Smell processing in the brain
The olfactory bulb, ventral to the frontal cortex (between Frontal Cortex and Cribiform Plate), then to the Amygdala, then Thalamus (also to Orbifrontal Cortex and to Piriform Cortex)
Stereochemical Theory of Olfaction
Shape of molecules indicating their size. Seven ‘primary’ smells
The receptors for smell are found in;
The Olfactory Epithelium; size of a postage stamp in the nose
What is the main destination of the lateral olfactory tract?
The Orbitofrontal Cortex
How many types of odorant receptors are found in the human nose?
about 400
