What is the difference between the sinoatrial node and the atrioventricular node?

The SA (sinoatrial) node generates an electrical signal that causes the upper heart chambers (atria) to contract. The signal then passes through the AV (atrioventricular) node to the lower heart chambers (ventricles), causing them to contract, or pump. The SA node is considered the pacemaker of the heart.

Keeping this in consideration, what is the atrioventricular node?

The atrioventricular node or AV node is a part of the electrical conduction system of the heart that coordinates the top of the heart. It electrically connects the atria and ventricles.

Furthermore, why is sinoatrial node also called pacemaker? Answer and Explanation: The SA (sinoatrial) node is called "pacemaker" because it is a group of cells in the wall of the right atrium that have the ability to

Also to know, what type of cells are the sinoatrial and atrioventricular nodes?

The SA node is also called the sinus node. The electrical signal generated by the SA node moves from cell to cell down through the heart until it reaches the atrioventricular node (AV node), a cluster of cells situated in the center of the heart between the atria and ventricles.

How does the sinoatrial node work?

SA node (sinoatrial node) – known as the heart's natural pacemaker. The impulse starts in a small bundle of specialized cells located in the right atrium, called the SA node. The electrical activity spreads through the walls of the atria and causes them to contract. This forces blood into the ventricles.
