Where does phrenic pain refer to?
from the hemidiaphragm or liver capsule to the ipsilateral shoulder
Where do visceral afferent fibers synapse from GI nerves?
the DORSAL horn of the spinal cord
What does prolonged afferent activity lead to?
Facilitation
What is facilitation?
maintenance of a pool of neurons at partial or subthreshold excitiation…. less afferent stimulation is needed to trigger the idscharge of impulses
What was that thing in red she put in about viscerosomatic pain?
- Visceral disturbances can cause activation of somatic muscle activity
- Visceral pathology results in somatic changes paraspinally
What is the percutaneous reflex of Morely?

What is lower GI sympathetics?
Distal duodeum to transverses colon is T10-11
the rest is T12-L2
What spinal segement do sympathetics end at?
L2!!!!!!!
What contributes to the celiac ganglion?
T5-9… greater splanchnic n.
