Antrioventricular node

  1. Nov 3, 2004 #1
    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?!? :rofl:

    Thanks in advance.

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