Answer

a-6

b-1

c-3

d-4

e=5

f-2

Explanation:

The sequence shows synaptic transmission across  

The arrival of action potential at the presynaptic neuron,prompted the influx of calcium ions on the presynaptic membrane to the axoplasm.

This leads to the fusion of the  synaptic vessels with the post synaptic membrane,These empty their contents of neurotransmitters into the synaptic cleft.

The neurotransmitter e.g acetycholine  crosses the cleft to bind with the receptors on the postsynaptic membrane,

The leads to the opening of ligand gated sodium channels which leads to the transmission of the action potential as Post Synaptic Potentials.

This is transmitted along the axon of the postsynaptic neuron,as post synaptic potential which can either be excitatory or inhibitory
