Term
| an unpleasant sensory and emotional experience associated with actual and potential tissue damage |
|
Definition
|
|
Term
| somatic sensory receptors |
|
Definition
| provides awareness of touch, sensation and pain |
|
|
Term
|
Definition
|
|
Term
|
Definition
| free nerve endings (pain receptors) that transduce noxious stimuli into nerve impulses. |
|
|
Term
|
Definition
| skin, muscle, connective tissue, circulatory system, and abdominal pelce and thoracic viscera |
|
|
Term
|
Definition
| represents the conversion of pain stimuli into a neuronal action potential, at level of peripheral nerves |
|
|
Term
|
Definition
| conduction of action potential, neuronal action potential transmitted through the cns for pain to be percieved |
|
|
Term
|
Definition
| (neospinaothalamic tract)mylenated (fast transmission), 10% of sensory fibers, sensation of sharp, stinging, cutting, pinching pain, transmitted to thalamus where pain first enters consciousness |
|
|
Term
|
Definition
| relates more to total pain experience, maximum intensity or duration of pain that a person is willing to endure before the person wants something done about pain. (psychological, familial, cultural and environmental factors influence) |
|
|
Term
|
Definition
| closely associated with the point at which a stimulus is percieved as painful. threshold to pain is fairly uniform from one person to another |
|
|
Term
|
Definition
| unmylenated, small daimeter, slowest rate of conduction. warm hot sensation, mechanical, chemical, heat and cold induced pain sensation. |
|
|
Term
| slow wave, 2nd pain, slower onset, longer duration. believed to be responsible for central sensitization to chronic pain |
|
Definition
|
|
Term
|
Definition
| mylenated. fastest rate of conduction. convey cutaneous pressure, touch sensation, cold sensation, mechanical pain, heat pain. |
|
|
Term
| fast pain, 1st pain, typically mechanical or thermal |
|
Definition
|
|
Term
|
Definition
| relays info about 4 major modalities. touch, temp, PAIN, and body position. |
|
|
Term
|
Definition
| the region of the body wall that is supplied by a single pair of dorsal root ganglia |
|
|
Term
|
Definition
| pain that originates from pathology of the nervous system. When peripheral nerves are affected by injury or disease it can lead to unusual and sometimes intractable sensory disturbances. |
|
|
Term
| widespread pain that is not otherwise explainable, evidence of sensory deficit, (numbness, paresthesia) burning pain, pain that occurs with light stroking of skin, and attacks of pain that occur without seeming provocation |
|
Definition
|
|
Term
| What is responsible for stimulating pain response |
|
Definition
| pressure (injury) then, chemical mediators stimulate dermatomes and nociceptors. |
|
|
Term
| fractured ankle, which nerve fibers are stimulated? |
|
Definition
|
|
Term
|
Definition
| less than 6 months, quick, 1st pain, A fibers |
|
|
Term
| what chemical mediators stimulate dermatomes? |
|
Definition
| prostaglandin and bradykinin |
|
|
Term
| T or F. Some nerves are highly selective of the stimuli they respond to and others respond to multiple stimuli |
|
Definition
|
|
Term
|
Definition
| Substance P, Glutamate and aspartate |
|
|
Term
|
Definition
| extremely important in moving impulse from peripheral nerve through spinal cord to CNS, excites pain response |
|
|
Term
|
Definition
| Lower activation threshold and causes sensitization. |
|
|
Term
|
Definition
| Lower activation threshold, cause sensitization of CNS, and helps trigger impulse to neurons that extend to the midbrain. (so stimuli can be moved up through CNS) |
|
|
Term
|
Definition
| degree a person can ignore the pain |
|
|
Term
|
Definition
| major organs, referred pain |
|
|
Term
| pain in the internal organs and abdomen, poorly localized as a result of the lessesr number of nociceptors, underlying cause mostly disease process, appendicitis, colon cancer |
|
Definition
|
|
Term
|
Definition
| older adults have increased threshold to pain. peripheral neuropathies, skin thickness changes, decrease in pain tolerance |
|
|
Term
|
Definition
| inhibiting or changing of pain impulse. |
|
|
Term
| descending inhibitory mechanisms |
|
Definition
| certain nociceptive stimuli can activate these pathways reducing pain. structures located in spinal dorsal horn, (reticular formation, periaqueductal grey, cerebral cortex ie; brain) net effect: blocked or diminished pain signal |
|

Term
| who are the two BEST nursing classmates ever? |
|
Definition
| Katie Fitzpatrick and Tori Mitchell!! :) haha |
|
|
Term
| endogenous antinociceptive mediators |
|
Definition
| enkephalins, endorphins, dynorphins (opiate like chemicals within body) |
|
|
Term
| exogenous mediators (pain meds) |
|
Definition
| bind to opiate receptors in body |
