Where do preganglionic neurons synapse with postganglionic neurons in the sympathetic nervous system?.
FinnZ [79.3K]

Preganglionic axons synapse at the sympathetic chain ganglia with a postganglionic neuron. The postganglionic neuron then leaves the sympathetic chain ganglia through a gray ramus communicans (unmyelinated axons) and reenters the spinal nerve and travels to the skin and blood vessels throughout the body.
