AI Thread Summary
The atrioventricular node (AVN) is a specialized section of nodal tissue located on the right side of the partition that divides the atria, specifically near the bottom of the right atrium. It functions as a critical component of the heart's electrical conduction system, acting both like muscle tissue by contracting and generating nerve impulses, similar to nervous tissue. This dual functionality classifies the AVN as a patch of neuromuscular cells, confirming its role in coordinating heartbeats by transmitting signals throughout the heart wall.

Antrioventricular node...

What exactly is the AVN? I know what it does, but what is it? From all the sources I have read I have been told its 3 things:
a) a patch of muscle cells,
b) a patch of fibrous tissue,
c) a patch of neuromuscular cells,

Which is it?!? :smile:

Thanks in advance.

What is the atrioventricular node?

* The atrioventricular (AV) node is a section of nodal tissue that lies on the right side of the partition that divides the atria, near the bottom of the right atrium.

What is a node?

* A node is a specialized type of tissue that acts like both muscle and nervous tissue. When nodal tissue contracts (like muscle tissue) it generates nerve impulses (like nervous tissue) that travel throughout the heart wall.

Does that therefore mean that it is "a patch of neuromuscular cells" if we refer to my previous list?
 
Yes it is a patch of neuromuscular cell.
