There are two pacemakers in the heart. One (which is the main pacemaker of the heart) can be found in the upper right-most part of the right atrium and the other one can be found in the center most part of the heart, inside the atrio-ventricular wall.

Are autorhythmic cells located only in the interventricular septume?

Not exclusively:Cardiac Muscle cells are either contractile cells or autorhythmic cells. The majority are contractile.Examples of autorhythmic cells:Sinoatrial (SA), or Sinus, NodeAtrioventricular (AV) NodeAtrioventricular (AV) Bundle (occasionally referred to as the bundle of His)Right and Left Bundle BranchesPurkinje Fibers


What does auto-rhythmic mean?

Autorhythmic cells (pacemakers) refers to the cardiac muscle cells responsible for synchronizing the contractile cells to coordinate a heart contraction.

Autorhythmic cells (pacemakers) refers to the cardiac muscle cells responsible for synchronizing the contractile cells to coordinate a heart contraction.


How do the waves of depolarization generated by the autorhythmic cells spread to the muscle cells?

Autorhythmic cells in the heart generate electrical impulses that spread through the atria and ventricles via specialized conduction pathways, such as the atrioventricular node, bundle of His, and Purkinje fibers. These pathways allow for coordinated depolarization of the muscle cells, ultimately leading to contraction of the heart chambers.


What are autorhythmic fibers?

They are fibres which generate AP(action potential) which trigger heart contractions.


What would a nonfunctional sinoatrial node do?

It would cause the heart to stop beating in a autorhythmic fashion.


Which type of muscle tissue is autorhythmic?

cardiac muscle


What type of muscle would be considered autorhythmic?

Cardiac muscle is considered autorhythmic, meaning it has the ability to generate its own electrical impulses without the need for external stimulation. This property allows the heart to beat independently of nerve input.


Is a pacemaker a group of cells located in the left atrium?

A pacemaker is a device inserted into the heart to regulate the heart beats or heart rate


Where are the cells that initiate the stimulus for contraction of the heart muscle located?

SA node


What is the common name for the sinoatrial node?

which of the following applies to the sinoatrial node? a)it is a mass of nerve cells b)it produces important enzymes c)it generates autorhythmic impulses to the contractthe heart d)it contains both bicuspid and tricuspid valves


Where is the cardiac muscle cell located?

Cardiac muscle cells are located in the walls of the heart. They are responsible for pumping blood throughout the body.
