The potential difference across the resting membrane.

Vedclass · Answer

(A) The electrical potential difference across the plasma membrane of a resting neuron is known as the resting membrane potential.In a resting state,the axonal membrane is more permeable to potassium ions $(K^+)$ and nearly impermeable to sodium ions $(Na^+)$.Consequently,the interior of the axon contains a high concentration of $K^+$ and negatively charged proteins,while the exterior contains a high concentration of $Na^+$.This ionic gradient,maintained by the $Na^+-K^+$ pump,results in the inner surface of the membrane being negatively charged relative to the outer surface,typically measured at approximately $-70 \ mV$.
