5 True/False questions
In regards to the cardiac plexus, where does parasympathetic input arise from? → Cervical ganglia.
Describe the lumbo-sacral lateral chain → Located in the neck. All presynaptic input enters from T1 w/ minor contributions from T2 & T3. Cervical lateral chain ganglia are fused.
What occurs with sympathetically mediated pain? → There is a sensitization of peripheral (C-fibers) & central (dorsal horn laminae 1& 2).
Blocking what ganglion is indicated in painful conditions of the lower extremities and pelvic viscera and vascular insufficiency in the legs? → Superior hypogastric plexus & ganglion impar
Describe the wind-up theory. → Involves repetitive noxious stimuli (c-fibers)->prolonged discharge of dorsal horn cells-> progressive ↑ in APs per stimulus->long term potentiation (LTP).
