Sternum

A bone that forms the front and middle portion of the rib cage; also called the breastbone or breast plate.

AV Node

The atrioventricular node, a part of the heart's electrical system that acts as a gatekeeper, slowing the electrical current before it passes from the atria to the ventricles.

SA Node

The sinoatrial node, also known as the heart's natural pacemaker, is a cluster of cells situated in the right atrium of the heart that regulates the heart's rhythm by generating electrical impulses.

Bundle of His

A collection of heart muscle cells specialized for electrical conduction that transmits the electrical impulses from the atrioventricular node to the ventricles of the heart.
