Generation and Conduction of Nerve Impulse

Two neurons, $A$ and $B$, synapse onto a third neuron, $C$. If neurotransmitter from A opens ligand-gated channels permeable to ${\mathrm{Na}}^{+}$ and ${\mathrm{K}}^{+}$ and neurotransmitter from $\mathrm{B}$ opens ligand-gated ${\mathrm{Cl}}^{-}$ channels, which of the following statements is true?

During generation of an action potential, depolarisation is due to:

Resting membrane potential of a neuron is approximately:

In the resting state of the neural membrane, diffusion due to concentration gradients, if allowed would drive

Action potential in neurons is generated by a rapid influx of

Nerve cells do not divide because they do not have

During synaptic transmission of nerve impulses, the neurotransmitter$\left(\mathrm{P}\right)$ is released from synaptic vesicles by the action of ions$\left(\mathrm{Q}\right)$. Choose the correct $\mathrm{P}$ and $\mathrm{Q}$ .

Unidirectional transmission of nerve impulse is maintained by

The potential difference in the membrane which is responsible for the conduction of an impulse is brought about by a change in the membrane

Chemical transmission in synapse occurs due to
