Autonomics and Somatic Reflexes Flashcards
(32 cards)
autonomic nervous systems
2 neuron systems
-preganglionic and postganglionic
parasympathetics
craniosacral
CN III, VII, IX, X
S2-4
long preganglionic
synapse at terminal ganglia - effector ganglion
ACh - pre and postganglionic
parsympathetic cause
diarrhea urination pupil contract bradycardia bronchospasm emesis lacrimation salivation
when treating autonomics
nerve forget the OA
we “balance” the autonomics
vagus nerve
exits jugular foramen
-close to OA
sympathetics
T1-L2 fight/flight short preganglionic long postganglionic paraspinal ganglia more divergence
Ach - preganglionic
NE - postganglionic
IMLCC
cell bodies of sympathetics
white rami communicantes
preganglionic
only T1-L2
gray rami communicantes
postganglionic
innervation to extremeties
not by PS
sympathetic only**
enteric NS
two plexus
submucosal and myenteric
in GI system
influenced by autonomics
visceral afferents
nociceptive fibers travel with symapthetics**
non-nociceptive with parasympathetics
vagus nerve
mostly afferent fibers
PAN
primary afferent nociceptors
- small unmyelinated
- ex/ C fibers
- naked nerve endings
- can experience sensitization
- high energy stimuli
somatosomatic reflex
DTRs
withdrawal
viscero-visceral reflex
gut distension > contraction
baroreceptor reflex
viscero-somatic reflex
cardiac disease > somatic dysfunction T1-5
somato-visceral reflex
spinal manipulation > change in HR, BP, sympathetic activity to kidney and adrenal medulla
convergence projection theory
referred pain
- visceral and somatic afferents converge on same or associated neurons
- viscero-somatic or somato-somatic pain
viscero-somatic reflexes cause
non-neutral type II lesions
- single segment
- same side rotation and side bending
facilitation
area of restriction develops lower threshold for irritation and dysfunction when other structures stimulated
less negative RMP
- hyperirritable or hyperresponsive
- muscles hypertonic
tender point
aka jones points
small hypersensitive point in myofascial tissues of body used as diagnostic criteria
-NOT A DIAGNOSIS**
without radiation**
abrupt lengthening of muscle
-spindle fibers - reflex contract pulls on antagonistic *creates dysfunction
travells points
aka trigger points
hypersensitive palpable nodule
- painful with referred pain
- active and latent
treat with soft tissue, deep massage, injection, MET, myofacial stretch
active travell point
refer pain at rest, with muscle activity, or with palpation
