Question 24

Where is the pain located if it is sharp/pricking/vibrating and easily located?

Answer 24

superficial at the skin

Question 25

Where is the pain located if it is dull/achy/heavy and more difficult to localize?

Answer 25

musculoskeletal

Question 26

Where is the pain located if it is aching in quality and frequently referred superficially?

Answer 26

visceral

Question 27

elicited by activation of nociceptive tissues in the body in the absence of tissue damage

Answer 27

transient pain

goes away without treatment. Ex. touching something hot and moving away quickly

Question 28

If actual tissue damage occurs, relatively short duration pain with defined etiology. May be localized and have a reflex mechanism initiated for protection from damage

Answer 28

acute

Question 29

longer duration, often persisting longer than typical for a condition

Answer 29

chronic/persistent

often inadequate response to appropriate care and associated with more emotional reactions

Answer 31

neuropathic

Question 32

what kind of pain is usually accompanied by signs or symptoms of neurological dysfunction, such as paresthesias, itching, anesthesia, weakness?

Answer 32

neuropathic

radicular vs referred pain

Question 33

T/F Only nociceptive pain can be both acute or chronic

Answer 33

F Both nociceptive and neuropathic pain can be acute and become chronic

Answer 34

radicular pain

Question 35

pain that occurs away from the origin/source of pain is called

Answer 35

referred pain

may be acute or chronic

Question 36

specific pain receptors transmit signals to a pain center in the brain and that’s how they perceive pain

Answer 36

specificty theory

Question 37

people feel pain when a specific pattern of neural activity occurs regardless of what neurons are activated

Answer 37

pattern theory

Question 38

_______ control pain by binding to specific opioid receptors

Answer 38

opiopeptins - endorphins, enkephalins, dynorphins

Question 39

The ___________ releases opiopeptins in times of emotional stress and results in a raised pain threshold.

Answer 39

endogenous opioid system
