Pacemaker cells and node cells are not exactly the same, but they are closely related. Pacemaker cells are specialized cardiac muscle cells responsible for initiating and regulating the heartbeat, primarily found in the sinoatrial (SA) node, which is the heart's primary pacemaker. The term "node cells" typically refers to the cells within the SA node and the atrioventricular (AV) node, both of which play critical roles in the conduction system of the heart. Thus, while all pacemaker cells are node cells, not all node cells are pacemaker cells.
What else can I help you with?
What is the back-up pacemaker of the heart?
The sinoatrial node is known as the pacemaker of the heart.
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.
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.
Is AV NODE known as pacemaker?
No, it is the SAN (sinoatrial node)
What is considered the pacemaker of the heart?
The sinoatrial node is considered the pacemaker of the heart.
What is the technical term for your pacemaker?
The heart's "pacemaker" is the SA (sinoatrial) node.
The sinoatrial node is the heart's?
... pacemaker.
What is natures pacemaker?
sinus node
What is the main pace maker of the heart?
The primary pacemaker of a normal healthy heart is the sinus node (or SA node). It is located in the right atria of the heart.
Which heart structure does the pacemaker substitute?
The SA Node.
What is the internal pacemaker of the heart called?
SA node (Sinus Node)
What is the sa node?
The SA node is the "pacemaker" of the heart. Cells in the SA node are called "pacemaker" cells and they direct the contraction rate of the entire heart by generating action potentials.
