A

is the process by which pain signals are relayed from the periphery to the spinal cord and then to the brain

25
where do the primary afferent fibers terminated when transmitting
in the dorsal horns
26
what does the dorsal horn do
it integrates and modulates the periphery
27
what are the three segments of transmission
1- transmission along the peripheral nerve fibers to spinal cord 2- dorsal horn processing 3- transmission to the thalamus and the cerebral cortex
28
what are dermatones
are areas on the skin that are innervated primarily by a single spinal cord segment
29
what is central sensitization
is increased sensitization and hyperexcitability of neurons in the CNS
30
what is allodynia
the epxerience of significant pain from touch or tactile stimulation in and around the area of tissue or nureve injury
31
what can untreated acute pain lead to
acute pain can lead to chronic pain through the process of central sensitization
32
what is neuroplasticity
the process that allow neurons in the brain to compensate for injury and adjust their responses to new situations or changes in their environment
33
what does central sensitization of the dorsal horn result in
1 hyperalgesia 2 painful responses to normally innocuous stimuli 3 prolonged pain after the original noxious stimuli ends 4 the extension of tenderness or increased pain sensitivity outside of an area of injury to include uninjured tissue
34
what is referred pain
location of pain reported by the person with an injury or a disease involving visceral organs
35
how do fibers from the dorsal horn enter the brain
through the spinothalamic tract and the spinoreticular tract
36
what are some ways to target pain in the transmission stage
opioid analgesics
37
what is perception
occurs when pain is recognized, defined, and assigned meaning by the individual experiencing the pain
38
what is the reticular activating system responsible for in the perception stage of pain
for warning the individual to attend to the pain stimulus
39
what is the somatosensory system responsible for
responsible for localization and characterization of pain
40
what is the limbic system responsible for in the perception stage of pain
for emotional and behavior responses to pain
41
what is the cortical structure responsible for in the perception stage of pain
crucial to constructing the meaning of pain
42
what is modulation
involves the activation of descending pathways that exert inhibitory or facilitatory effects on the transmission of pain
43
what type of drugs exert their effects on modulation of pain
antidepressants
44
what is nociceptive pain
normal processing of stimulus that damages normal tissue or has the potential to do so if prolonged
45
what is neuropathic pain
abnormal processing of sensory input by the peripheral or central nervous system
46
what is the treatment of nociceptive pain
typically a nonopioid or an opioid
47
what is the treatment of neuropathic pain
typically includes adjuvant analgesic
48
what causes nocicpetive pain
damage to the somatic or visceral tissue
49
characteristics of superficial pain
sharp burning prickly
50
characteristics of deep pain
deep aching throbbing
51
what causes viceral nociceptive pain
activation of nociceptors in the internal organs and body cavities- respond to inflammation, stretching, and ischemia
52
what are the signs and symptoms of neuropathic pain
described as numbing, hot, burning, shooting, stabbing, sharp, or electric shock-like it is sudden intense, short lived or lingering
53
what are common causes of neuropathic pain
trauma, inflammation, metabolic disease, alcoholism, infections of the nervous system, tumors, toxins, and neurologic diseases
54
what is differentation pain
pain that results from loss of afferent input secondary to either peripheral nerve injury or CNS injury
55
what is sympathetically maintained pain
pain that is associated with dysregulation of the autonomic nervous system
56
what cause central neuropathic pain
is caused by CNS lesions or dysfunction
57
onset of acute pain
sudden
58
onset of chronic pain
gradual or sudden
59
duration of acute pain
less than 3 months or as long as natural healing to occur
60
what is the duration of chronic pain
longer than 3 months- may start as an acute injury but continues past normal time for recovery
61
cause of acute pain
generally can identify a precipitating event- surgery or illness or trauma
62
cause of chronic pain
may not be known, original cause of pain may differ from mechanisms that maintain pain
63
course of acute pain
decrease over time and goes away as recovery occurs
64
course of chronic pain
typically pain does not go away | periods of remission and exacerbation
65
typical physical and behavioral manifestations of acute pain
``` may vary but can reflect sympathetic nervous system activation - ^ HR, RR, BP - diaphoresis - pallor anxiety agitation confusion urinary retention ```
66
typical physical and behavior manifestations of chronic pain
``` predominantly behavioral manifestations - flat affect decreased physical activity fatigue withdrawal from social interaction ```
67
what is breakthrough pain
pain in patients who have a baseline of pain that is mild to moderate but fairly controlled
68
what is end- of - dose failure
pain that occurs before the expected duration of specific analgesic
69
why did the bicycle fall over
because it was two tired
70
what is sciatica
pain that follows the course of the sciatic nerve- it may originate from muscles or joints around the back or from compression or damage to the sciatic nerve
