Q.
The given diagram shows axon terminal. Select the option that correctly matches the steps in transmission of impulses (list i - vii) with the labellings (A - C) in diagram
(i) Chemicals called neurotransmitters are released in the synaptic cleft through ion channels
(ii) When an impulse arrives at the axon terminal, it stimulates the movement of synaptic vesicles
(iii) Neurotransmitters are endocytosed into the neurons
(iv) The ion channels close w ith the binding of neurotransmitters to their specific receptors vesicles
(v) Synaptic vesicles move towards the membrane where they fuse with the plasma membrane
(vi) Neurotransmitters are released in the synaptic cleft.
(vii) The released transmitters bind to their specific receptors on post-synaptic membrane.
