Question

Quizplus · Accepted Answer

All cells, including excitable and nonexcitable tissues, have a resting membrane potential and gated ion channels. The threshold potential is only found in excitable cells, so it is not a characteristic found in all cells. Mechanically-gated channels may be present in some cells, but are not a universal characteristic of all cells.
