Once Inside the Sympathetic Chain Ganglion, the Preganglionic Fiber May

Question

Once inside the sympathetic chain ganglion, the preganglionic fiber may:
A)synapse with a sympathetic postganglionic neuron.
B)send ascending and/or descending branches through the sympathetic trunk to synapse with postganglionic neurons in other chain ganglia.
C)pass through one or more ganglia without synapsing.
D)do all of the above.

Accepted Answer

The preganglionic fiber may synapse with a sympathetic postganglionic neuron within the same ganglion, send ascending and/or descending branches through the sympathetic trunk to synapse with postganglionic neurons in other chain ganglia, or pass through one or more ganglia without synapsing. Therefore, all of the above options are possible.
