Can someone please help me with this sensory neurons question?

Place the events involves in generating action potential in sensory neurons in the order in which they occur:

1) The neurotansimtter released from pre-synaptic terminal(s) of the sensory neuron.

2) Action potential is evoked in the trigger zone of the axon belonging to the sensory neuron.

3) The "receptor potential" is transmitted electrotonically to the trigger zone of the axon.

4) Action potential arrives at the pre-synaptic terminal of the axon causing release of neurotransmitter.

5) Threshold depolarisation occurs in the trigger zone of the axon.

6) Stimulus acts on the receptor and causes a local depolarisation of the cell membrance known as tge " receptor potential"

7) Action potential evoked in the trigger zone of the axon spreads electrotonically to the adjacent region of the axon (e.g. the nearest node of Ranvier in myelinated axons), causing threshold depolarisation and a generation of action potential in that region.
