pain Flashcards
(17 cards)
how do we feel pain
nervous system transmission
body modulation of pain
mind intrepretation of stimuli and their meaning
nociception
neural process of encoding noxious stimuli
this i the neural input pain is the output
process of pain
transduction
conduction
transmission
perception
transduction
conversion of nocious stimuli into an action potential
conduction
pasage way of axion potentionals towards cns
transmission
synpatic transfer of input from one neuron to another
perception
sensation is perceived by the brain
A fibres
myelinated fibres
fast, sharp, localised pain
lateral spinothalamic tract
precise location
C fibres
unmyelinated fibres
slower conduction
slow dull ache burning pain
spinothalmic and spinoreticular tract
poorly localised
trigeminal tract
transmit fast and slow pain from face
A and C fibres
how do we classify pain
duration- (Acute, sub-acute, chronic)
pathophysiology
nocieptive
neuropathic
nociplastic
duration of pain
acue- up to 6 weeks
sub-acute - 4-12 weeks
chronic- last more than 3-6 months
nociceptive pain
actual or threatned tissue damage
activation of nociceptors
neuropathic pain
pain arises from abnormal neural activity
pain related to lesion of tissue
nociplastic
arises from altered nociception
no sitmulus
fibromyalgia
where dos modulation of pain occur
receptor
dorsal horn
suprapsinal structures
treat pain
acute- decrease peripheral inflammatory process= allow healing
chronic- pain reduction/ promotion of optimal life
