Zoology - Neural Control and Coordination Question with Solution | TestHub

During the resting-state of the neuron:

- The high concentration of K+ and negatively charged proteins and low concentration of${\mathrm{N}\mathrm{a}}^{+}$in axoplasm.

- In contrast, the fluid outside the axon contains a low concentration of${\mathrm{K}}^{+}$, a high concentration of${\mathrm{N}\mathrm{a}}^{+,}$and thus forms a concentration gradient.

- These ionic gradients across the resting membrane are maintained by the Na-K pump which actively transports$3{\mathrm{N}\mathrm{a}}^{+}$outwards for$2{\mathrm{K}}^{+}$into the cell.

- The membrane is polarised.

- Potential difference is termed as resting potential.
