5 True/False questions
What type of neuron leave the ganglia and travel to segmental nerves & target organs? → Postgagnlionic neurons (unmyelinated C fibers).
What forms the stellate ganglion? → Inferior cervical ganglion fuses w/ T1.
Describe the dorsal horn changes that occur w/ sympathetically mediated pain. → A-beta fibers form abnormal connections in shallow laminae (1 & 2)->normal sensory input interpreted as high intensity noxious stimuli.
↑ gene expression for receptors for pain related neurotransmitters (substance P).
↓ opioid binding sites.
Where do the celiac ganglion (collateral ganglion) receive its input? → From the greater & lesser splanchnic nerves.
Where is the cervical sympathetic chain located? → Located in the neck. All presynaptic input enters from T1 w/ minor contributions from T2 & T3. Cervical lateral chain ganglia are fused.
