What is action potential?
Understand the Problem
The question asks for a definition of action potential and briefly touches on related concepts like resting potential and depolarization. It seems to be related to muscle physiology.
Answer
An action potential is a sequence of changes in the membrane voltage of a cell, especially in muscle and nerve cells, when stimulated.
An action potential is a sequence of changes that occur in the potential when a muscle is stimulated. It involves a resting potential, depolarization and repolarization.
Answer for screen readers
An action potential is a sequence of changes that occur in the potential when a muscle is stimulated. It involves a resting potential, depolarization and repolarization.
More Information
Action potentials are essential for nerve and muscle cell communication. They involve rapid changes in voltage across the cell membrane, allowing signals to be transmitted quickly and efficiently.
Tips
A common mistake is to confuse action potential with resting membrane potential. Action potential involves a rapid change from negative to positive and back again in the membrane voltage, while resting membrane potential is the stable voltage of a cell when it is not stimulated.
