What are the components of the cardiac conduction system?

This group of muscle cells is called the cardiac conduction system. The main parts of the system are the SA node, AV node, bundle of HIS, bundle branches, and Purkinje fibers.

What are the components of the cardiac conduction system quizlet?

The components of the cardiac conduction system include the SA node, the AV node, the AV bundle, the AV bundle branches, and the Purkinje cells.

What are the 5 parts of the conduction system in order?

The cardiac conduction system comprises the following structures in order: SA node, internodal pathway and Bachmann’s bundle, AV node, bundle of His, bundle branches, and Purkinje fibers.

What are the 4 steps to cardiac conduction?

4 Steps of Cardiac Conduction

1. Step 1: Pacemaker Impulse Generation. The first step of cardiac conduction is impulse generation.
2. Step 2: AV Node Impulse Conduction.
3. Step 3: AV Bundle Impulse Conduction.
4. Step 4: Purkinje Fibers Impulse Conduction.

What is the cardiac conduction system quizlet?

A system of specialized non-contractile cardiac muscle cells without sarcomeres which conduct electrical impulses that stimulate the heart to beat (contractile muscle cells).

What is the cardiac conduction pathway?

The conducting system of the heart consists of cardiac muscle cells and conducting fibers (not nervous tissue) that are specialized for initiating impulses and conducting them rapidly through the heart (see the image below). They initiate the normal cardiac cycle and coordinate the contractions of cardiac chambers.

Which component of the heart conduction system consists of the normal pacemaker of the heart quizlet?

The heart’s rhythm of contraction is controlled by the sinoatrial node (SA node), often called the pacemaker. This node is part of the heart’s intrinsic conduction system, which is made up of specialized myocardial cells called nodal cells.

Which component of the heart conduction system consists of the normal pacemaker of the heart?

The SA node is sometimes called the heart’s “natural pacemaker.” When an electrical impulse is released from this natural pacemaker, it causes the atria to contract. The signal then passes through the atrioventricular (AV) node.

Which component of the cardiac conduction system is located between the ventricles?

Which part of the cardiac conduction system is located in the lateral walls of the ventricles? The Purkinje fibers are located in the lateral walls of the ventricles.

What is the component of the cardiac conduction system known as the pacemaker?

The sinus node is sometimes called the heart’s “natural pacemaker.” Each time the sinus node generates a new electrical impulse; that impulse spreads out through the heart’s upper chambers, called the right atrium and the left atrium (figure 2).

Which of the following is not part of the cardiac conduction system?

atrioventricular (AV) valve is NOT part of the intrinsic conduction system of the heart and therefore the correct answer.

Which component of the conduction system is located between the ventricles quizlet?

Which of the five main components of the cardiac conduction system travels down the ventricular septum?

Bundle of His This fiber bundle receives the electrical signal from the AV node and carries it to the Purkinje fibers. The bundle of His runs down the length of the interventricular septum, the structure that separates your right and left ventricles.

Which component of the electrical conduction system is the pacemaker quizlet?

What is the cardiac conduction system and its function?

The cardiac conduction system is a network of specialized cardiac muscle cells that initiate and transmit the electrical impulses responsible for the coordinated contractions of each cardiac cycle.

Which component of the cardiac conduction system is located between the ventricles and splits into left and right branches?

The atrioventricular bundle (bundle of His) extends from the node, traveling through the central fibrous body, to the basal ventricular septum, adjacent to the membranous septum. It then splits into both its right and left bundle branches.

Which components of the cardiac conduction system serves as the pacemaker?

Which component of the electrical conduction system is the pacemaker?
