Flashcards in EXAM #2: OSTEOPATHIC CONSIDERATIONS IN GI Deck (38)
What nerve provides 75% of the PNS influence on the body?
CN X (Vagus)
What nerves compose the cranial portion of the PNS?
CN III, VII, IX, X
What nerves compose the sacral portion of the PNS?
S2, S3, S4
What are the effects of increased PNS stimulation on the glands, GI, Liver, Gallbladder/ ducts, GI arterioles?
Glands= copious secretions
GI= stimulation of peristalsis and sphincter relaxation
Liver= promote glycogen synthesis
GI arterioles= NO innervation
What ganglia are associated with the SNS?
T1 - L2
How does the SNS supply the head and upper extremity?
Cervical ganglia (CN II, V, VII)
What is the SNS supply to the lower extremity?
Lumbar splanchnic nerves
What is the SNS effect on the Glands, Blood Vessels, GI, Liver, Gallbladder, and GI arterioles?
Glands= decrease secretion
GI= decrease peristalsis and increase sphincter tone
Liver= promote glycogen breakdown
GI arterioles= constriction
What type of tone is typically seen during disease or trauma?
Increased SNS tone
What are the effects of increased SNS tone in a disease state?
1) Vasoconstriction leading to decreased nutritional supply to tissue
2) Thickened secretions causing tissue congestion
3) Decreased lymphatic drainage
Clinically, what is the osteopathic viewpoint on the clinical impact of increased SNS tone in disease?
Impaired medication delivery
How do patients present with lymphatic congestion in regards to their appearance and palpatory ques?
- Appearance= uncomfortable
- Palpation= boggy/soggy
What is proper lymphatic motion dependent on?
Contractions of the diaphragm
What is the most important diaphragm to treat to improve lymphatic flow?
What types of receptors relay the stretch that happens in the GI tract?
- Pacinian corpusles
- Free nerve endings
Describe the viscero-somatic relationship.
- Visceral pain is carried by visceral afferent"
- There is "spill-over" into the somatic afferents
What thoracic levels are associated with the Upper GI System?
What throacic levels are associated with the Lower GI System?
In the thoracic vertebrae, what type of SD is commonly seen with a chronic GI issue?
All TOWARD the SAME side of the organ involved.
What is post-op ileus a consequence of?
Viscero-visceral reflex in response to handling of the bowel during during surgery
What ganglia will afferents from the thoracic splancnic nerves go to?
What ganglion will afferents from lumbar splancnic nerves go to?
Inferior mesenteric ganglion
What is the outcome of hyperactivity of both the SNS and PNS?
What are the three main elements that will hinder lymph flow?
1) Flattened diaphragm
2) Fascial torsion
3) Thoracic inlet impairment
What lumbar segments correspond to the left crus?
What lumbar segments correspond to the right crus?
What viscero-somatic reflexes correspond to the stomach?
SNS= T5-9 on left
What viscero-somatic reflexes correspond to the gallbladder?
What viscero-somatic reflexes correspond to the liver?
