"___ is an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage"

Pain

1

2 theories of pain

Specific and gate control theory

2

Which theory explains the amount of pain is related to the amount of tissue injury and accounts for many types of injuries but does not explain psychological contributions?

Specific Theory

3

Which theory explains the complexities of the pain phenomenon?

Gate control theory

4

What is the perception of pain?

nociception

5

How many neurons are in the perception of pain?

3

Primary order, Secondary order and Third Order

6

Which order of neurons bare nerve endings in skin, muscle, joints, arteries, and viscera that respond to chemical, mechanical and thermal stimuli?

Primary

7

Which order of neurons can detect a wide range of of stimuli? A-delta fibers and Unmyelinated C polymodal fibers

Primary

8

What are examples of low-threshold mechanical information that can distract from injury pain?

Touch, vibration and pressure

9

Which neurotrasmitters excite pain?

glutamate and aspartate

10

Which neurotransmitters inhibit pain?

serotonin, GABA and endorphins

11

What is threshold depolarization from direct stimuli?

Direct excitation

12

What is threshold depolarization from inflammatory mediators after tissue injury?

Indirect excitation

13

An example of ___ excitation is increased sensitivity due to inflammatory mediators like in sunburn.

Indirect

14

What is the point at which a stimulus is perceived as pain?

pain threshold

15

T/f The pain threshold does not vary significantly among people or in the same person over time.

True

Crazy I know.. word for word off his slide

16

T/F Intense pain at one location may cause an decrease in the threshold in another location

False

It increases the threshold in another location

17

Duration of time or the intensity of pain that a person will endure before initiating pain responses and influenced by cultural perceptions, expectations, role behaviors and physical and mental health can be described as

Pain tolerance

18

Decreased with repeated pain, fatigue, anger, boredum, apprehension and sleep deprivation and generally increased by alcohol consumption, persistent use of pain medication hypnosis can be described as

pain tolerance

19

Point at which stimulus is perceived as pain is called

pain threshold

20

Pain at one location may cause an increase in the threshold in another location is called

perceptual dominance

21

Duration or time or the intensity of pain that a person will endure before initiating pain responses is called

pain tolerance

22

What are two classifications of pain?

Nociceptive pain: pain with normal tissue injury (somatic, visceral)

Non-nociceptive pain: neuropathic pain (peripheral and central)

23

This type of pain arises from connective tissue, muscle, bone and skin. When activated by A-delta fibers, is the pain sharp or dull? Is the pain well localized or poorly localized?

Acute somatic pain.

Since it is activated by A-delta, the pain is sharp and well-localized.

Pain activated by C-fibers is poorly localized and dull.

24

This type of pain is in the internal organs and abdomen, poorly localized due to lesser number of nociceptors.

Acute visceral pain.

25

This is pain in an area removed or distant from its point of organ. What type of pain is this?

Referred pain

- MI pain is described as referred pain.

26

This type of pain is a misinterpretation of nociceptive input. The cause of this type of pain is unknown, and is also defined as pain lasting longer than 3 months. What type of pain is this describing?

CHRONIC PAIN.. or medicaid pain.. whichever you like..:)

27

What are the most common types of chronic pain?

- Back pain (most common)
- Myofascial pain syndrome (injury to the muscle and fascia)
- Chronic postoperative pain
- Cancer pain

28

This type of pain is most often chronic, and is typically the result of trauma or disease of nerves. What type of pain?

Neuropathic pain

29

Phantom limb pain and complex regional pain syndrome are both characteristics of what type of pain?

Neuropathic pain
