synapses are

gaps between the presynaptic and postsynaptic neuron, and they can be electrical or chemical in nature

synapses are interfaces that are important in

allowing communication between an axon terminal of a presynaptic neuron and the dendrites of a postsynaptic neuron as a result of action potential

synapses allow communication between

presynaptic neurons and postsynaptic neurons

neurons communicate with one another via

electrochemical signals known as action potentials

specifically, an action potential travels down the

signaling cell (presynaptic neuron) until it reaches the axon terminals

axon terminals

are responsible for signal transmission across the synapse and to the postsynaptic neuron

at chemical synapses

an action potential in the presynaptic neuron results in the release of neurotransmitters, which bind receptors on the membrane of the postsynaptic neuron
