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?

  • yellow
  • green
  • orange
  • red

8. What is amplitude measured in?

  • dB
  • Hz
  • nm
  • um

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

  • red, green, blue
  • red, green, yellow
  • red, yellow, blue
  • green, black, red

14. What is frequency measured in?

  • Hz
  • W
  • dB
  • N

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

  • eye colour
  • mood

19. What is the opponent pair of black?

  • yellow
  • green
  • white
  • red

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)
