Vagus
PNS Heart, Lungs, esophagus, upper GI, small intestine, kidneys, ascending and transverse colon, upper ureter
Pelvic Splanchnic
PNS Colon, rectum, reproductive organs, bladder, pelvis, lower ureter
Two functions of the enteric nervous system
1) Sustaining local reflex activity independent of CNS
2) Complex interactions btwn ANS and CNS
Autonomic distribution of the parasympathetic NS
No Extremities
No vasacular
Visceral is same is SNS - smooth muscle , cardiac muscle, Nodal and glandular tissue in thoracoabdominopelvic cavity
Sensitization
A reflex modifier
Progressive amplification of a response following repeated stimulus, one stimulus is terminated the neurons return to baseline
Habituation
A reflex modifier
Decrease in response to a stimulus after repeated exposure to the stimulus over time, allows is to “tune out”, once stimulus is terminated the neuron returns to baseline
Fascilitation
Maintenance of a pool of neurons in a state of subthreshold excitation; less afferent stimulation is required to trigger the discharge of impulses
Characteristics of viscerosomatic reflexes
Tend to exhibit non-neutral (Type II) SD
- Increased moisture and temperature
- Poorly defined endpoint (rubbery feel)
- Usually affect small rotators
Sympathetic ANS treatment considerations
-Appropriate spinal levels
-Paraspinal muscle spasms
-Rib restrictions
-Distal ganglia; cervical, celiac & mesentary
(Chapman Reflexes)
Parasympathetic ANS treatment considerations
Vagus: condylar compression, OA & AA SD
Sacrum: sacral somatic dysfunction
(Chapman Reflexes)
