Questions and Answers

What is the role of the sinoatrial (SA) node in the cardiac conduction system?

The sinoatrial (SA) node generates normal electrical impulses in the heart.

Describe the function of the atrioventricular (AV) node.

The atrioventricular (AV) node serves as a gateway for electrical impulses to travel from the atria to the ventricles.

How do Purkinje fibers contribute to heart function?

Purkinje fibers conduct electrical impulses throughout the cardiac muscle.

Study Notes

Cardiac Conduction System

The cardiac conduction system is a specialized network of cardiac muscle cells responsible for coordinating heart contractions.
The network is made of modified muscle cells and includes the Purkinje fibers, a system of specialized cells that quickly conduct electrical impulses within the heart muscle.
The sinoatrial (SA) node, located in the right atrium, is the heart's natural pacemaker, initiating electrical impulses that trigger heartbeats.
The atrioventricular (AV) node, located between the atria and ventricles, acts as a gatekeeper, delaying the transmission of electrical impulses from the atria to the ventricles, ensuring proper coordination of heart contractions.
