A

25
Q

three groups of general senses

A

exteroceptors, proprioceptors, interoceptors

26
Q

general sense group that relays info about external environment

A

exteroceptors

27
Q

general sense group that depict body position in space

A

proprioception

28
Q

these receptors sense tissue damage

A

nociceptors

29
Q

nociceptors perceive blank

A

pain

30
Q

nociceptors are blank nerve endings with large receptive field

A

free

31
Q

nociceptors are found everywhere except blank

A

brain

32
Q

nociceptors provide a blank function

A

protective

33
Q

nociceptors do not blank well

A

adapt

34
Q

three types of pain

A

fast, slow, referred

35
Q

prickling pain that is quick and induces a reflex and usually ends when stimulus ends

A

fast pain

36
Q

type of pain that is burning and begins later, persists longer, and is achy

A

slow pain

37
Q

type of pain that is visceral pain that feels like it is coming from a more superficial region

A

referred pain

38
Q

example of a referred pain

A

brain freeze

39
Q

referred pain is due to blank structures being innervated by the same blank nerves as the damaged viscera

A

superficial, spinal

40
Q

pain in left arm before heart attack is blank pain

A

referred

41
Q

receptors that involve heat and cold

A

thermoreceptors

42
Q

thermoreceptors are free nerve endings in blank

A

skin

43
Q

thermoreceptors are blank to adapt

A

quick

44
Q

hot and cold is detected by blank but pain is detected by blank

A

thermoreceptors, nociceptors

45
Q

six types of of tactile receptors in these two categories

A

unencapsulated, encapsulated

46
Q

three types of unencapsulated tactile receptors

A

free nerve endings, root hair, tactile disc

47
Q

unencapsulated tactile receptor that is in the papillary of dermis and is for general touch

A

free nerve endings

48
Q

unencapsulated tactile receptor that monitors distoritions and movement across body surface

A

root hair

49
Q

unencapsulated tactile receptor that is an expanded nerve terminal that synapses with Merkel cell and is sensitive to fine touch

A

tactile disc

50
Q

three encapsulated tactile receptors

A

tactile corpuscles, lamellated corpuscle, ruffini corpuscle

51
Q

encapsulated tactile receptor that is found where tactile sensitivities are very well developed

A

tactile (meissner’s) corpuscles

52
Q

encapsulated tactile receptor that responds to deep pressure

A

lamellated (Pacinian) corpuscle

53
Q

encapsulated tactile receptor that is in dermis and detects pressure with little adaptation

A

ruffini corpuscle

54
Q

stretch receptors that monitor changes in pressure and detect stretching of tissue walls

A

baroreceptors

55
Q

baroreceptors regulate blank activities

A

autonomic

56
Q

two autonomic activities regulated by baroreceptors

A

digestive tract, bladder, carotid sinus, lung, colon

57
Q

receptors that monitor position of joints, tension in tendons, state of muscle contraction

A

proprioceptors

58
Q

proprioceptors have blank adaptation to stimulus

A

no

59
Q

two types of proprioceptors

A

muscle spindles, golgi tendon organ

60
Q

muscle spindle proprioceptors monitor blank of muscle

A

length

61
Q

golgi tendon organ proprioceptors monitors blank in a tendon during contraction

A

tension
