Abdomen Flashcards
Movement of the viscera in response to voluntary movement or movement of the diaphragm in respiration
Visercal mobility
Inherent motion of the viscera themselves, independent of extrinsic forces (expect peristalsis)
Visceral motility
What are the 4 categories of visceral motion
- Somatic Nervous system2. ANS3. Craniosacral Rhythm4. Visceral Motility
What is somatic nervous system?
Voluntary motion of the musculoskeletal system
What is controlled by ANS
diaphragmatic motion, cardiac motion, peristaltic motion
What is considered foregut. What ganglia is associated with it and what innervates it from what spinal level?
esophagus to promixal duodenum (stomach, liver, pancreas, duodenum) – Celiac ganglia, greater splanchnic n. (T5-T9)
What is considered midgut. What ganglia is associated with it and what innervates it from what spinal level?
distal duodenum to proximal 2/3 of transverse colon (small intestine, R colon, Transverse colon) – SMG, lesser splanchnic n. (T10-T11)
What is considered hindgut, what ganglia is associated with it and what innervates it from what spinal level?
distal 1/3 of colon to rectum (transverse colon, L colon, pelvic organ) – IMG, least splanchnic n. (T12), lumbar splanchnic n. (L1-L2)
What innervates the PNS of upper GI
Vagus n.
What innervates the PNS of the lower GI and what spinal level?
pelvic splanchnic n. (S2-4)
What is innervated by the R. vagus nerve?
lesser curvature, pancreas, liver, gallbladder, Right colon
What is innervated by the L. vagus nerve?
greater curvature, pyloric sphincter
What does the pelvic splanchnic nerve innervate?
PNS of Left colon and pelvis.
What is controlled by the craniosacral rhythm?
circulation of CSF
What are the motions of visceral motility?
expir – clockwise toward midlineinspir – counter clockwise away from midline
