Do preganglionic neurons form gap junctions with postganglionic neurons?

Preganglionic neurons do not typically form gap junctions with postganglionic neurons. Instead, they communicate through synapses, releasing neurotransmitters that bind to receptors on the postganglionic neurons. This synaptic transmission is crucial for the modulation and propagation of signals within the autonomic nervous system. Gap junctions are more commonly found between neurons of the same type or in certain glial cells, facilitating direct electrical coupling.
