ANS/Homeostatic Review Flashcards
What regulates the ANS?
hypothalamus, limbic system, brainstem
What is the general organization of the ANS?
Most interneurons receive input from …
both a visceral nociceptor and somatic source
Where does the PNS arise? SNS?
PNS - brain stem nuclei and intermediate gray matter at S2-4 (CNS III, VII, IX, X)
SNS - arising from ICC of lateral horn (T1-12, L1-2)
Sympathetic innervations of…
Parasympathetic innervation of…
What is the function of the enteric nervous system?
- complex interactinos b/t ANS and CNS
- capable of sustaining local reflex activity independent of CNS
Where in the body do you find SNS? PNS?
What are the four types of reflexes?
Somatosomatic
Viscerovisceral
Somatovisceral
Viscerosomatic
What is sensitization? habituation?
What is facilitation?
maintenance of pool of neurons in subthreshold excitation state
once established, can be sustained by CNS activity
What SD do VS reflexes tend to show?
non-neutral (type II)
increased moisture, temperature; usually affects rotatores
What is allostasis?
process by which the body responds to stressors in order to regain homeostasis
What is allostatic load?
What are the transitional zones?
Where do lympathics receive innervation from?
SNS
SD may disable a pump
Viscerosomatic reflexes do not respond to…
OMT
What is included in the five model approach?
Biomechanical
Respiratory - Circulatory
Metabolic - Energetic
Neurologic
Behavioral
What are the goals of OMT to reestablish homeostasis and decrease energy expenditure?
