2. “This one goes to 11” … Actually, this is the main property of sound waves that provide us information on loudness

3. What is amplitude?

4. Mariah Carey’s high notes seem high because of this property of sound waves

5. What is frequency?

6. If a tree falls in the forest will it have a pure sound? The purity of sound waves gives us this perceptual characteristic of sound

7. What is timbre?

8. It takes the combination of these two theories to somewhat explain how we perceive pitch

9. What are place and frequency theory?

10. The transformation of sound waves into neural impulses takes place in this part of the cochlea

11. What is the basilar membrane?

12. These are the three types of “raw data” for which our sense of touch has receptors

13. What are pressure, temperature, and chemicals?

14. Sharp, localized pains are sent on the fast pathway via these fibers

15. What are A-delta?

16. This theory claims that a pattern of neural activity can block pain signals from being registered or sent by the brain

17. What is gate-control theory?

18. These fibers send the dull, aching pain signals along the slow pathway

19. What are C fibers?

20. This area in the midbrain is thought to be involved in sending signals away from the brain (using endorphins and serotonin) to reduce the perception of pain

21. What is the PAG (periaqueductal gray)?

22. This sense helps maintain our balance by responding to gravity and keeping us informed of our body’s location in space

23. What is the vestibular sense?

24. This is our sense for knowing the positions of various parts of the body

25. What is kinesthesis?

26. These shapely parts in the inner ear contain fluid and hair cells that help to let us know which way is up

27. What are the semicircular canals?

28. The receptors for our sense of bodily position are located mainly in these two types of location

29. What are the joints and muscles?

30. This disease is caused by an infection in the inner ear, and causes extreme dizziness

31. What is Meniere’s disease?

32. These are the real raw data for our sense of taste (and smell as well)

33. What are chemicals?

34. These are the four basic tastes for which we have receptors

35. What are sour, sweet, salty, and bitter?

36. This is the fancy name for our sense of taste

37. What is the gustatory sense?

38. These people have up to four times as many taste buds as the average person

39. Who are supertasters?

40. Taste buds are found on these bumps on the tongue

41. What are the fungiform papillae?

42. The sense of smell is the only one that isn’t routed through this relay station in the brain

43. What is the thalamus?

44. This is the technical name for the sense of smell

45. What is olfaction?

46. Impulses for smell are “planted” in this part of the brain before being sent to the cortex

47. What is the olfactory bulb?

48. Don’t joke around about these receptor cells for smell that are located at the top of the nasal passage

49. What are the olfactory cilia?

50. Our sense of smell is pretty good. In fact we can distinguish among this many different odors (but we have a hard time attaching names to them)

51. What is 10,000?
