Question

Explain why a change in extracellular Na did not alter the membrane potential in the resting neuron.

Answer 1

Step-by-step explanation:

A change in extracellular Na did not alter the membrane potential in the resting neuron because the plasma membrane of a neuron is composed of little Na+ leakage channels and it is slightly permeable to few Na, thus lead to reduction in diffusion if Na inside and outside the cells.
