The chemical synapse is bounded by the presynaptic neuron,from which neurotransmitters are released across the synaptic cleft, to the postsynaptic neuron where the receptors for that neurotransmitters are located.
Explanation:
Synapse is the junction between two neurons.
Typically a synapse involves junction between an axon terminal of one neuron called presynaptic neuron .and dendrites of a second neuron , known as post synaptic neuron.
Synapses can be of two types: A chemical synapse and an electrical synapse.
Electrical synapse involves , action potential conducts directly between adjacent cells through structures called gap junctions.
A chemical synapse involves chemicals called neurotransmitters for the transmission of action potential.
