Synapses are more like messages. There's a receiver (postsynaptic dendrite) and sender (presynaptic axon).
Picture axons as fruits. When the tree has them in lots, some are passed down (by buttons, in forms of ions and charges).
Electrical synapses are rarer, chemical are not. Similar to the popular social media apps are more common, why? Because everyone has them! Flexible, easy to use, quick.
The electrical ones are your VIP features on nervous system.
That's all for now! Stay tuned.
