Dendrite: This is like the mailbox where the postman picks up letters (or signals). Dendrites are branch-like structures that receive these signals from other neurons.
Axon: This is like the path or route that our postman takes to deliver his letters. The axon is a long slender projection of a neuron that conducts electrical impulses away from the neuron's cell body.
Synapse: This is like the destination address on each letter. Synapses are junctions between two neurons where communication occurs through neurotransmitters.
