Summary Introduction

To determine: The difference between the ventricular muscle cells and SA node based on their action potentials.

Introduction: Action potential refers to a massive change in membrane voltage that has a constant magnitude and can spread to adjacent areas of the membrane.

Summary Introduction

To determine: The mechanism responsible for pacemaker potential and also estimate its inherent rate.

Introduction: Pacemaker potential is a slow depolarization manifested by the SA node cells. It helps in bringing the membrane potential to the threshold. Threshold refers to the point at which the action potential takes place.

Summary Introduction

To determine: The mechanism that helps the SA node to function as the heart’s pacemaker.

Introduction: The SA node is defined as the natural pacemaker. The pacemaker plays an important role in controlling the heart rate by deciding the time of atrial contraction and ventricular contraction.
