6. Did females NOT on the pill prefer males with similar or different HLAs?
Different
Similar
7. How many distinct chemoreceptors are there on the tongue?
25
5
10
1
8. What is the McClintock effect?
Women are attracted to men with complementary immunity
Women living together will synchronise their menstrual cycles due to a pheromone found in sweat
Women do not synchronise their menstrual cycles
Humans have a functioning VNO, which affected mate choice based on pheromones
9. Taste receptors are located where?
In the pits of papilla
In the nose
On the surface of the tongue
On the epiglottis
10. What 2 things CAN'T you smell?
Methane and carbon monoxdie
Carbon monoxide and menthol
Methane and isobutylmethoxypyrazine
Carbon monoxide and isobutylmethoxypyrazine
11. At what concentration is Bitrex detectable at?
5 ppm
100 ppm
10 ppm
1 ppm
12. What is it that causes the experience of chilli peppers as hot?
Know one knows why
Receptors on the cell stimulated by physical heat are also stimulated by chilli heat
Chilli peppers reduce the activity of receptors on the cell that are stimulated by cold
Chilli peppers increase body temperature
13. What is the cycle time of the nose (during which different nostrils have different flow rates and smell different things)?
30 minutes
3 minutes
3 hours
1 hour
14. What is the role of turbinates?
To break up the flow of air and force it against the olfactory epithelium
To force air into the lungs
To stop the flow of air to allow time for olfactory receptors to detect oderants
To move mucus
15. What 2 things CAN you smell?
Menthol and isobutylmethoxypyrazine
Methane and isobutylmethoxypyrazine
Mentol and methane
Isobutylmethoxypyrazine and carbon monoxide
16. What were the results of Cain (1982)?
Men and women performed equally in identifying scents
Women performed better overall identifying scents, but men performed better for scents in the 'male domain'
Men performed better overall identifying smells, but women performed better for scents in the 'female domain'
Women performed better than men in identifying all scents
17. Is the taste sensory cortex lateralised?
Yes
May be
No
We cannot say because experimentally limiting taste to one side of the tongue is too difficult
18. True or false, the thalamus shows reliable activity even to odors below threshold?
True
False
19. What is the vibrational theory of odor receptors?
Lock and key theory - whether an odorant molecule smells the same or different to another is based on whether it has a complementary shape to the receptor binding site of the OSN
Whether a odorant smells the same or different to another is based on its IR vibrational spectrum
Molecules might have to be the right shape to ‘dock’ with receptor sites but then bond energies determine the final activation level
20. What is the swipecard model of odor receptors?
Lock and key theory - whether an odorant molecule smells the same or different to another is based on whether it has a complementary shape to the receptor binding site of the OSN
Molecules might have to be the right shape to ‘dock’ with receptor sites but then bond energies determine the final activation level
Whether a odorant smells the same or different to another is based on its IR vibrational spectrum
