Can an axon connect to dendrites of multiple other neurons? In a typical multi-polar neuron, an axon has multiple axon terminals that can connect to another neuron's dendrites.

Are there cases where an axon connects to dendrites of multiple neurons?
Sure, look at the connectome of C. elegans for example: URB (circled in red) has synaptic connections to IL1, RIC and also to CEP (which also synapses back to URB, showing that cycles in the connectome are possible). Likewise RIS (circled in blue) has synaptic connections to at least 4 different neurons (in this map) and a couple more off-map.
