Which of the following is a good analogy for synapses?

Question

a long stretch of highway

the wooden framing of a house

the plastic sheathing on an electrical cord

the spaces between stepping stones on a pathway

Answer 1

A good analogy for synapses is the spaces between stepping stones on a pathway.

This analogy works because just as the spaces between stepping stones allow for movement and connection while also providing gaps where you can pause, synapses are the junctions between neurons where signals are transmitted, allowing communication while also providing a space where neurotransmitters can be released and received.
