Question

chapters 10 and 11 nervous sys... the resting cell membrane is more permeable to which ion? multiple choice calcium sodium potassium magnesium

Explanation:

In a resting neuron, the cell membrane is more permeable to potassium ions ($K^+$) than to other ions like sodium, calcium, or magnesium. This is due to the presence of leak channels (especially potassium leak channels) that allow $K^+$ to move more freely across the membrane, contributing to the resting membrane potential.

Answer:

B. Potassium
