          Four statements are given below. 

          1. Neurotransmitters are released from vesicles.
          2. An impulse is generated in the postsynaptic neurone.
          3. An impulse arrives at the end of a neurone.
          4. Neurotransmitters diffuse across the synaptic cleft.

          Which of the following options correctly describes the sequence of events that occurs at a synapse?

          • 1 → 2 → 3 → 4

          • 2 → 4 → 1 → 3

          • 2 → 1 → 4 → 3

          • 3 → 1 → 4 → 2
