an action potential in one neuron can initiate an action potential in the other?

In order for a neuron to initiate an action potential it has to receive enough impulses to reach its threshold.
So if you imagine an analogy:
my phone starts ringing, it's people calling me to convince me to do something
after enough people call i make up my mind I'm going to do it

With this analogy I have compared phone calls to multiple stimulus from other neurons to the neuron in this video
What I'm calling phone calls they're calling "voltage gated sodium channels opening"

in this next video the phone calls in my analogy would be compared to acetylcholine


Acetylcholine  is a neurotransmitter in both the peripheral nervous system (PNS) and central nervous system (CNS) in many organisms including humans. Acetylcholine is one of many neurotransmitters in the autonomic nervous system (ANS) and the only neurotransmitter used in the motor division of the somatic nervous system. (Sensory neurons use glutamate and various peptides at their synapses.) Acetylcholine is also the principal neurotransmitter in all autonomic ganglia.
Acetylcholine slows the heart rate when functioning as an inhibitory neurotransmitter. However, acetylcholine also behaves as an excitatory neurotransmitter at neuromuscular junctions (like in the last video)
