Synapse
Definition
A synapse is a tiny gap at which nerve cells (neurons) communicate with each other. Information from one neuron flows to another neuron across this small space.
Analogy
Imagine you're playing catch with your friend across a small stream. You're on one side (representing one neuron), your friend is on another side (another neuron), and you throw balls (neurotransmitters) over the stream (synapse) for your friend to catch.

Neurotransmitter: These are chemical messengers that transmit signals across a synapse from one neuron to another 'target' neuron, muscle cell, or gland cell.
Receptor Site: These are specific areas on dendrites or neurons designed to receive specific neurotransmitters.
