2. Osteopathic Reflexes Flashcards
What is a D.O.?
Name the osteopathic reflexes.
- viscerosomatic
- somatovisceral
- viscerovisceral
- somatosomatic
relationship between an input stimulus to the body and an output action to either a muscle or a secretory organ
reflex
Describe myotaic reflex.
Dorsal horn neurons can respond to what type of stimuli?
visceral & somatic stimuli
“…Characteristics of reflex function as modulated by messages from other areas of the (1) _____ and by activity of the (2) ____ and (3) ____ systems.”
- nervous system
- endocrine system
- immune system
processing area of spinal cord
gray matter
upper layers 1-6 of spinal cord gray matter
components of lower layers
- interneurons
- motoneuron cell bodies
afferent fibers: visceral and somatic
afferent fibers: visceral and somatic
visceral afferents
activate sympatehtic outflows and skeletal muscle motor neurons
afferent fibers: visceral and somatic
reverse activation
somatic inputs later sympathetic and paraysympathetic outlfows
descending influences on reflexes
- visceral disturbances cause activation in the somatic musculature
- somati disturbances can alter visceral function
This is the basis for decompensation of homeostasis (basis for loss of health).
somatic component of disease
basis of the facilitated segment concept
sensitization
habituation
nociception theory: what 2 processes exist together to help maintain a homeostasis between over-reaction and under-reaction to a sitmulus?
facilitation
activation of nociceptive pathways
nociception theory
short term excitability - sensitization
- 1-2 seconds of afferent input
- excitability last for 90-120 seconds
long term excitability - sensitization
- inputs of several minutes
- excitability lasts for hours
fixation
- 15-40 minutes of afferent input
- excitability lasts for days or weeks
permanent excitability
- lasts forever (?) - a long time
- death of inhibitory interneurons
steps for increasing sensitivity of neurons
facilitated segment concept
allostasis
long-term neural effect of segmental facilitation
allostasis
allostasis
multiple effects on body systems affecting homeostasis
somatosomatic osteopathic reflex
localized somatic stimuli producing patterns of reflex response in segmentally related somatic structures
somatovisceral osteopathic reflex
localized somatic stimulation producing patterns of reflex response in segmentally related visceral structures
viscerosomatic osteopathic reflex
localized visceral stimuli producing patterns of reflex response in segmentally related somatic structures
