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.

Do heart cells have mitochondria?
Yes heart cells have.They are very active cells,they have lot of them
How does a liver cell differ from a heart cell?
brain cells are activated by brain genes and heart cells are activated by heart genes. that's how they function, by their genes
What is responsible for initiating the heartbeat?
There is a group of cells in the heart called the "pacemaker" that sends out a nerve shock to initiate a heartbeat. It also changes the pulse depending on certain external conditions to maintain homeostasis. -Richard
How many cells are in a heart?
Research hasn't shown just how many heart cells are present. It could be millions or it could be billions, but there are no definite number of cells on record as of yet. The heart cells assemble early in gestation, and they organize into a complex, densely packed environment with elaborate communication networks. Maybe eventually scientists will figure out just how many heart cells are in a normal, healthy heart.
How are the cells in the biceps alike to the cells of the heart?
They are both made up of muscle cells. The heart is made of cardiac muscle, and the biceps are made of skeletal muscle.
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.
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.
How do the waves of depolarization generated by the autorhythmic cells spread to the muscle cells?
Gap Junctions in the cell spread the action potential to nearby cells.
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
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.
Where is the cardiac tissue located?
In the heart
