1

1. Colorblindness

lacks 1 or more of the 3 pigments/cones (RBG)

2

2. What is projection?

A sensation that seems to come from the region being stimulated, in other words, where it came from

3

3. What kind of sense do Meissner's corpuscles and Pacinian corpuscles detect?

Pressure

4

4. Meissner's corpuscles (TACTILE CORPUSCLES)

light touch/motion, 2 neurons , connective tissue masses, hairless portions of skin ---> lips, palms, soles, fingertips, kiss/tickle, Very sensitive to light touch

5

5. Pacinian corpuscles

Heavy/deep pressure, 1 neuron larger connective masses deep in the skin ---> muscle tendons and joint ligaments, respond to deep pressure ---> punch

6

6. At what temp are pain receptors STIMULATED?

Heat - 113 and above Cold - 50 and below

7

7. What is referred pain and an example?

A pain feeling as though it's coming from another body part than where it's stimulated. EX: Heart attack, but felt in shoulder

8

8. What are endorphins and where are they found?

They are neuropeptides, for pain control/suppress and mood elevators. Found in the pituitary gland

9

9. Tension headache

Stress, sleep, posture, and muscle

10

10. Vascular (migraine) headache

Constriction of blood vessels

11

11. Diffraction of light rays

Bending of light around an object

12

12. Refraction of light rays

Bends light rays through an object

13

13. static and dynamic equilibrium

Static - still body, Dynamic - body in motion

14

14. NIB transducer

Converts energy from one form to another

15

15. Rhodopsin

Helps see in dim light

16

16. Anosmia causes

smoking, drugs(cocaine), inflamed nasal cavity

17

17. Synethesia

Hear music but see color

18

18. Chemoreceptors

response to chemical changes in the body; tongue and GI tract

19

19. Painreceptors

response to tissue damage; skin and throat

20

20. Thermoreceptors

response to changes in temperature; skin and tongue

21

21. Mechanoreceptors

response to changes in pressure; ear and skin

22

22. Photoreceptors

response to changes in light energy; eyes(rods/cones) and skin(tan)

23

23. SENSATION - PROJECTION - RESPONSE

The feeling, the source, the action

24

24. Sensory Adaptation

Receptors adapted due to decreasing impulses leading to stopping signals. EX: smelly room eventually stops smelling or dark room starts to adjust

25

25. Free nerve ending

- most superficial to skin found in epithelial tissue "itchy"

26

26. Heat most SENSITIVE

Between 77-113 (burning)

27

26b. Cold most SENSITIVE

Between 50-68 (freezing/burning)

28

27. Muscle cramp

Squeezing of capillaries that interrupts blood flow -"ischemia/c"

29

28. Visceral pain

Deep in the body

30

29. Referred pain

Feels like it's coming from a different part of the body, cerebral, cortex may incorrectly interpret information

31

30. Acute pain fibers

Carried by thin; myelinated fibers, Associated with SHARP/INTENSE pain, Arises from skin and superficial tissues, Immediate

32

31. Chronic pain fibers

- Carried by thin, unmyelinated fibers, Associated with DULL/ACHING pain, Arises from organs or deep tissues, Later, long-lasting,

33

32. Cerebral Cortex determines

pain intensity, locates the source, and gives a response,

34

33. Natural pain killers

Serotonin stimulate the release of enkaphalins ---> sent to suppress and block chronic pain, Endorphins, serotonin, and enkaphalins are all natural pain killers

35

34. Olfaction(smell)

Olfactory organs

36

35. Gustation(taste)

Taste buds

37

36. Audition(Hearing and equilibrium)

Ears

38

37. Vision(sight)

Eyes

39

38. Taste buds

Found on tongue, roof of mouth, and pharynx

40

39. Papillae

elevations on the tongue

41

40. For something to be tasted

it must be dissolved

42

41. 5 taste sensations

sweet, sour, salty, bitter, and umami(savory/delicious/all combined)

43

42. How do we differentiate smell?

Smells come in different shapes

44

43. What do we smell with?

cilia

45

44. Where does smell go?

The olfactory bulb

46

45. What is smell related to?

emotion and memory

47

46. How many smell receptors do humans have?

5 million

48

47. what is a NOSE?

Someone who creates scents in perfume business

49

48. 3 parts of perfume

1. Top note - most volatile, evaporates fastest. EX citrus 2. Middle note: floral 3. Base note: biggest molecules, evaporate longest. EX- musk, earthy, sandalwood

50

49. Do we taste with fungi form papillae?

NO

51

50. Taste is the sense that....

keeps us going, SURVIVING

52

51. Poisons are...

Bitter

53

52. Taste is a social sense.

EX - Out to eat, fine meal, etc.
