Within a fraction of a ____ \(\mathrm{K}^{+}\)diffuses ____ the membrane and restores the resting potential of the membrane at the site of excitation and the fibre becomes once more responsive to further stimulation.
1 Second, inside
2 Minutes, outside
3 Second, outside
4 Minutes, inside
Explanation:
Within a fraction of a second, \({{\rm{K}}^{\rm{ + }}}\) diffuses outside the membrane and restores the resting potential of the membrane at the site of excitation and the fibre becomes once more responsive to further stimulation.

In resting stage, the axonal membrane for negatively charged proteins found in axoplasm is
1 Permeable
2 Partially permeable
3 Impermeable
4 Selectively permeable
Explanation:
In resting stage, the axonal membrane is comparatively more permeable to potassium ions \({{\rm{K}}^{\rm{ + }}}\) and nearly impermeable to sodium ions \({\rm{N}}{{\rm{a}}^{\rm{ + }}}\). Similarly, the membrane is impermeable to negatively charged proteins present in the axoplasm

The most abundant intracellular cation is
1 \(\mathrm{H}^{+}\)
2 \(\mathrm{K}^{+}\)
3 \(\mathrm{Na}^{+}\)
4 \(\mathrm{Ca}^{++}\)
Explanation:
The most abundant cation in the intracellular fluid (ICF) is potassium \(\left(\mathrm{K}^{+}\right)\); whereas, the most abundant cation (or positively charged ion) in the extracellular fluid (ECF) is sodium \(\left(\mathrm{Na}^{+}\right)\).
