osteopathic reflexes Flashcards
myotatic reflex
contraction in response to a stretching force
where do afferents synapse (spinal cord gray matter)
posterior horn upper layers 1-6
what synapses in layers 3,4
mechanoreceptors
what synapses in layers 1 and 5
a(delta) fast pain fibers
what synapses in layer 2
small c fibers of slow pain
what is the basis for activation of the somatic m activity seen with visceral disturbances
the overlap between visceral and somatic afferent fibers
what is the somatic component of disease
musculoskeletal palpatory findings may correlate with visceral disturbances
what is habituation
process of decreasing response of a neural pathway with a continuous stimulation
ubiquitous phenomenon
opposite sensitization
what works together to maintain homeostasis between over-reaction and under-reaction of afferents
habituation and sensitization
what does secondary hyperalgesia develop
central sensitization
somatosomatic reflex
localized somatic stimuli producing patterns of reflex response in segmentally related somatic structures
somatovisceral reflex
localized somatic stimuli producing patterns of reflex response in segmentally related visceral structures
viscerosomatic reflex
localized visceral stimuli producing patterns of reflex response in segmentally related somatic structures
viscerovisceral reflex
localized visceral stimuli producing patterns of reflex response in segmentally related visceral structures
withdrawal response
a somatosomatic reflex response that occurs when a noxious stimuli is applied to a somatic structure
example of viscerovisceral reflex
distention of the gut results in increased contraction of the gut muscle
example of viscerosomatic reflex
heart attack – pain up shoulder, down arm
3 component characteristics of a chapman reflex
viscerosomatic reflex
gangliform contraction
a consistent reproducible series of points both anterior and posterior related to specific organs or conditions
characteristics of pain of a chapman point
pinpoint, sharp, non-radiating
pain is greater than expected
pt usually unaware of sore spot
for a chapman reflex, how long do you continue the moving pressure
10-30 seconds
contraindications of CR
anytime a pt needs emergent care
patient refusal
relative contraindicated w/ a fracture, cancer, and other patient instability
