None
What are the effects of the parasympathetic system on the GI musculature?
Peristalsis and relaxed sphincter
What are the effects of the parasympathetic system on the liver?
Promotes glycogen synthesis
What are the effects of the parasympathetic system on the Glands?
Copious secretions
What spinal levels are the ganglia located at?
T1 - L2
What are the effects of the sympathetic system on the glands?
Decreases secretions
What are the effects of the sympathetic system on the blood vessels?
constriction
What are the effects of the sympathetic system on the GI musculature?
Decreases peristalsis
What are the effects of the sympathetic system on the gallbladder?
Relax
What are the effects of the sympathetic system on the GI arterioles?
constriction
When is increased tone most often seen?
Disease or trauma state
What happens to lymphatics with increased sympathetic tone?
Decreased flow
What are the sympathetic nerves that supply the head and upper extremity?
Cervical ganglia
What are the sympathetics to the Lower extremities?
Lumbar splanchnic nerves
What happens when there is a decrease in lymphatic flow?
Boggy/spongy tissue with lower pH
What happens when there is a flattening of the diaphragm?
Decreases the volume displacement and pressure gradient leading to decreased lymphatic drainage, congestion, and decreased CO
What is the most important diaphragm for increasing lymphatic flow?
Inlet
Look at the table for viscero-somatic reflexes
What are the nerve organ bits that are located in the GI tract?
Pacinian corpuscles and free nerve endings
Visceral pain is poorly localized. What is the supposed effects along the spine?
SDs
What is the progression of pain sensation in the abdomen?
Visceral (poorly localized)
Somatic (well localized)
What are the spinal levels that are affected with the upper GI?
T5-T11
What are the spinal levels that are affected with the lower GI?
T9-L2
Which side are paraspinal muscles tight on with abdominal pain?
Same side as the involved organ
What happens when there is handling of the bowel?
Causes secondary viscero-visceral reflexes
Increased sympathetic tone leads to what problems in the GI system?
Increased vascular tone, reducing flow to the tissues
What is the effect of sympathetic overtone on the GI mucosa?
Increases its sensitivity to pH
What happens to sympathetic overtone with the gallbladder?
Relaxes
Thoracic splanchnic nerves go where?
Celiac ganglion
Lumbar splanchnic afferents go where?
Inferior mesenteric ganglion
What connects that first 2 cervical nerves?
CN X
What does the left/anterior vagus innervate in the GI system?
Stomach and duodenum
What does the right/posterior vagus innervate in the GI system?
Small intestines, right colon, and organs and glands up to the mid transverse colon
True or false: everything innervated by the vagus are intimately bound together and are capable of readily transmitting reflexes
True
What do S2-4 innervate in the GI tract?
Descending colon and rectum
What happens when there is hyperactivity of both the symp and parasymps?
IBS
What happens to nutrition with impaired lymphatic flow?
impaired d/t increased fibrosis
What is the innervation of the left crus? Right?
Left = L1-2 Right = L1-3
What is the effect of symp overtone on the crus?
Increased tautness of the tissues, decreases lymphatic flow
What are the attachment sites of the diaphragm?
costal cartilages of 7-12, xiphoid process
Innominate and sacral dysfunctions may lead to what?
Torsions within the levator ani musculature, thus tethering the sigmoid colon and rectum
Right shoulder pain can be suggestive of what?
gallbladder pain
Why do you treat the OA with GI complaints?
Where vagus exits
What type of motion should be used to increase parasympathetic tone?
Slow
What does addressing the sacrum do for the GI?
S2-4 nerves
What spinal levels do you want to look at in the ribs?
T5-12
What are the lymphatic treatments for the GI?
Myofascial release
Diaphragm
Pect traction
Lymph pump
