Answer:

Key points

Neurons communicate with one another at junctions called synapses. At a synapse, one neuron sends a message to a target neuron—another cell.

At a chemical synapse, an action potential triggers the presynaptic neuron to release neurotransmitters. These molecules bind to receptors on the postsynaptic cell and make it more or less likely to fire an action potential.
