Five events in the transmission of nerve impulse across the synapse are given below : A. Opening of specific ion channels allows the entry of ions in the post-synaptic neuron. B. Neurotransmitter bind

Question

Five events in the transmission of nerve impulse across the synapse are given below :

A. Opening of specific ion channels allows the entry of ions in the post-synaptic neuron.

B. Neurotransmitter binds to the receptor on post synaptic membrane

C. Synaptic vesicle fuses with pre-synaptic membrane, neurotransmitter releases into synaptic cleft.

D. Depolarization of post-synaptic membrane

E. Arrival of action potential at axon terminal. In which sequence to the events occur?

Accepted Answer

Answer: E → C → B → A → D — When an impulse (action potential) arrives at the axon terminal, it stimulates the movement of the synaptic vesicles towards the membrane where they fuse with the plasma membrane and release their neu
