Resting, Graded and Action Potentials: Where to Begin Your Revision

When revising nerve physiology, start by asking what each term describes: a baseline state, a local change, or a travelling signal. This reading companion introduces the free SelfHug lesson published on 25 October 2026.

Three questions for your next study session

What establishes a resting membrane voltage? How can local inputs combine? Why does a stronger stimulus not simply make each action potential taller? Use these questions to explain a diagram aloud before memorising its labels.

The full guide compares the signals, works through an illustrative neuron example and provides revision questions with answers.
