Ch7 - Oflaction Flashcards
1
Q
Stimulus
A
volatile substances w 15-300 molecular weight, almost all lipid soluble & organic origin
2
Q
Oflactory processing
A
each receptor sends 1 axon into olfactory bulb where it forms synapses with dendrites of mitral cells - axons of mitral cells travel to brain through olfactory tracts
3
Q
Recognition of odours
A
up to 10 000 diff odorants for humans - 339 diff olfactory receptors (min) - particular odour = particular pattern of activity in glomeruli - patterns of activity in posterior piriform cortex - odorant molecules bind to multiple receptors
