|
acute pain
|
uncomfortable or hurtful short-term sensation
|
|
|
chronic pain
|
uncomfortable or hurtful long-term sensation
|
|
|
nociceptors
|
pain receptors
free nerve endings located throughout body |
|
|
Ao fibers
|
sensory neuron wrapped in myelin
signals sharp, well defined pain |
|
|
C fibers
|
unmyelinated sensory neuron
conducts dull, poorly localized pain signals |
|
|
substance P
|
neurotransmitter responsible for continuing pain message to other neurons
controls whether or not pain signals will stop or continue to brain |
|
|
endogenous opioids
|
chemicals produced naturally w/i body that decrease or eliminate pain
acts similar to morphine group of neurotransmitters: - endorphins - dynorphins - enkephalins |
|
|
analgesic
|
drug used for pain relief
classifications: *non-narcotic *narcotic |
|
|
cyclooxygenase
|
enzyme responsible for formation of prostaglandins
NSAIDS inhibit these |
|
|
NSAIDS
|
drugs that inhibit cyclooxygenase
cyclooxygenase -> resonponsible for formation of prostaglandins -> prostaglandins activate peripheral nociceptors -> nociceptors produce pain |
|
|
bradykinin
|
chemical mediator of pain
follows tissue damage |
|
|
prostaglandin
|
chemical released after tissue damage
leads to pain, inflammation, etc. |
|
|
narcotic
|
drug capable of producing numbness or stupor-like condition
includes opioids |
|
|
opiates
|
natural narcotic extracted from poppy seeds
includes morphine & codeine |
|
|
opioid
|
natural or synthetic morphine-like substance
|
|
|
mu
|
type of opioid receptor affecting:
- analgesia - decreased GI motility - respiratory depression - sedation - physical dependence activated by: - pure opioid agonist (morphine & codeine) - mixed opioid agonist (buprenorphine) |
|
|
kappa
|
type of opioid receptor affecting:
- analgesia - decreased GI motility - sedation activated by: - pure opioid agonist (morphine & codeine) - mixed opioid agonist (pentazocine & butorphanol) |
|
|
antipyretic
|
reduces fever
|
|
|
tension headache
|
muscles of head/neck area become tight
due to stress & tension |
|
|
