Question

When exactly the polarisation of neuron membrane take place?

• A. Neuron is stimulated
• B. No impulse to transmit
• C. ${Na}^{+}$ ions rush in
• D. $K^{+}$ ions rush out

Answer 1

The correct option is B

No impulse to transmit

When a neuron is not stimulated or when there is no impulse to transmit, we consider the state as polarised membrane. This also means that the electrical charge on the outside of the membrane is positive while the electrical charge on the inside of the membrane is negative.
