Detailed Solution

Sequence of events of synaptic transmission:

(c) Action potential arrives at the presynaptic terminal, causing synaptic vesicles to fuse with the membrane and release neurotransmitters into the synaptic cleft.

(a) Neurotransmitters released into the synaptic cleft bind to specific receptors on the postsynaptic membrane.

(d) Binding of neurotransmitters to receptors triggers the opening of ion channels in the postsynaptic membrane.

(b) The opening of ion channels leads to changes in membrane potential, generating a new potential in the postsynaptic neuron, either excitatory or inhibitory, depending on the type of neurotransmitter and ion channels involved.
