6. What is the third step from photo receptor to sensation?
- Information from the eye meets at the optic chiasm
- Information is re-routed to the thalamus and then to the visual cortex in the occipital lobe
- Information is sent to ganglion cells via bipolar cells
- Information is sent up the optic nerve to the brain
7. What is the opponent pair of blue?
8. What is amplitude measured in?
9. What is the fourth stage of the hearing process?
- sound travels down the ear canal
- the ossicles vibrate onto oval window
- sound reaches the eardrum/tympanic membrane
- impulses travel along the auditory nerve
- waves are created in the fluid of the cochlea
- cilia on the basilar membrane fire action potentials
10. What types of wave is sound?
- Mexican wave
- transverse wave
- pressure wave
- sound wave
11. What happens to the photo pigment when light is projected onto it?
- breaks down (bleaching)
- changes colour
- sends electrical impulses
- activates vision
12. What happens to the 8% of people who lose their sense of smell?
- less interest in sex
- less interest in food
- less attracted to their partner
- less ability to taste flavors
13. What are the primary colours of light?
- red, green, blue
- red, green, yellow
- red, yellow, blue
- green, black, red
14. What is frequency measured in?
15. What has been found about the sense of smell?
- there is high adaptation - the ability to detect odour drops to 30% overtime
- there is high adaptation - the ability to detect odour drops to 50% overtime
- there is low adaptation - the ability to detect odour increases by 30% overtime
- there is no adaptation - out sense of smell stays the same throughout our lifetime
16. What is the final step from photo receptor to sensation?
- Information is sent to ganglion cells via bipolar cells
- Information is re-routed to the thalamus and then to the visual cortex in the occipital lobe
- Information is sent up the optic nerve to the brain
- Information from the eye meets at the optic chiasm
17. What is an example of an accessory structure?
- the lens of the eye
- the ear canal
- eyelashes
- fingers
18. Which factor does not affect taste?
- texture
- smell
- eye colour
- mood
19. What is the opponent pair of black?
20. What is the issue with the 'Trichromatic theory'?
- Dichromats can see yellow (the sensation from bleaching red and green iodopsin)
- Dichromats can see blue (the sensation from bleaching red and green iodopsin)
- Dichromats can see yellow (the sensation from bleaching blue and green iodopsin)
- Dichromats can see green (the sensation from bleaching yellow and green iodopsin)
