What else can I help you with?
Are the purkinje fibers commonly known as the natural pacemaker?
No, the purkinje fiber is not the natural pacemaker. The sinoatrial node (SA node) is the natural pacemaker of the heart.
What is the back-up pacemaker of the heart?
The sinoatrial node is known as the pacemaker of the heart.
What is the vital force that keeps your heart beating?
The vital force that keeps your heart beating is the electrical signals generated by the sinoatrial node, also known as the heart's natural pacemaker.
What component of the heart's conduction system is considered to be the heart's pacemaker?
Furkinje Fibers
Why the sino atria node is regarded as a pacemaker in the heart?
The sinoatrial, or SA, node is known as the pacemaker of the heart. There are other potential pacemakers if the SA node fails, but it is the main pacemaker.
What are the group of cells that ajust the heart beat?
The group of cells responsible for adjusting the heart rate are known as the sinoatrial node (SA node) and the atrioventricular node (AV node). The SA node generates the electrical impulses that initiate each heartbeat, while the AV node delays the impulse to allow the atria to contract before the ventricles. Together, these nodes help regulate the heart rate and ensure proper coordination of heart contractions.
Which is the area of specialized nervous tissue in the heart that is known as the pacemaker of the heart?
sinoatrial node
What is primary pacemaker of heart?
The human heart started out as a enlarged blood vessel that appears as two blood vessels coming together. The heart is comprised of four chambers two small chambers called the atrium and two large chambers known as the ventricles. There are several tissue layers of the heart. The internal layer is known as the endocardium the muscle layer is known as the myocardium, and the outer layer is known as the epicardium. There is an outermost sac called the pericardium that makes up a cavity in the thoracic cavity known as the mediastinum. There are specialized conducting cells or tissue within the myocardium of the heart. These specialized tissue performs the electrical conduction of the heart. The first is the sinoatrial node or the SA node found in the right upper atrium, the next one is the atrioventricular node or the AV node found in the right lower atrium. Then there is a group of this tissue known as the bundle of His or AV bundle (found in the wall of the ventricular septum (the dividing wall between the two ventricles)) and then the right and left buncle branches ( found also in the wall of the intraventicular septum and the outer ventricles) until you come to the purkinjie fibers at the end in the walls of the ventricles. The primary pacemaker of the heart is the SA node and depending on what is going on with the heart as far as damage the secondary pacemaker is the AV node, however the bundle of His could become a pacemaker site or the right and left bundle branches. The lower you go in the pacemaker sites the slower and less able the heart is to conduct proper electrical stimulation to effect the heart conduction and contraction (beat of the heart).

What is a BBB in the heart?
This si known as a Bundle Branch Block - and refers to an anomaly of a blockage in the nerve system of the heart at the bundle branches.
What Special tissue in right atrium that regulates heartbeat?
The sinoatrial (SA) node, also known as the pacemaker of the heart, is a special tissue located in the right atrium that acts as the natural pacemaker for the heart. It generates electrical impulses that regulate the heartbeat by initiating each heartbeat and setting the rhythm for the heart.
What is the hearts. pacemaker?
The heart's pacemaker, known as the sinoatrial (SA) node, is a cluster of cells located in the right atrium. It generates electrical impulses that initiate each heartbeat, regulating the heart's rhythm and rate. The SA node responds to the body's needs, adjusting the heart rate during activities such as exercise or rest. This natural pacemaker ensures coordinated contractions of the heart muscle, promoting efficient blood circulation throughout the body.
What is another name for atrioventricular bundle?
The Atrioventricular Bundle is also known as the Bundle of His. This conducts impulses and divides in ventrical to form fibers of Purkinge .
