Chapter 7: OLFACTION Flashcards
1
Q
How many olfactory receptors?
A
6 million
2
Q
olfactory epithelium?
A
- the epithelial tissue of the nasal sinus that covers the cribriform plate
- contains the cilia of the olfactory receptors
3
Q
How does olfactory processing work?
A
- each receptor send 1 axon into an olfactory bulb
- in there it forms synapses with dendrites of mitral cells
- then axons of mitral cells travel to the brain through olfactory tracts
4
Q
How many odours can humans recognize?
A
10 000
5
Q
How many diff olfactory receptors?
A
339
6
Q
How do we recognize a particular odour?
A
-recognizing a particular pattern of activity in the glomeruli
7
Q
How do odorant molecules send info to our brain’
A
- bind to multiple receptors
- stimulate olfactory neuron
8
Q
How are odorants associated with particular objects perceived?
