B)K⁺. C)intracellular anions (e.g. ,proteins). D)H⁺. E)Na⁺,K⁺ and intracellular anions are all important.

Question

Quizplus · Accepted Answer

The resting potential in neurons is primarily established through the differential distribution of sodium (Na+), potassium (K+), and various intracellular anions (e.g., proteins). These ions contribute to the negative charge inside the neuron compared to the outside, creating the electrical gradient necessary for nerve impulse transmission.
