The heart consists of two kinds of muscle cells:
Contractile cells
Conducting cells
#Id: 3960
Contractile cells constitute the majority of atrial & ventricular tissues.
#Id: 3961
Conducting cells constitute tissues of the SA node, the atrial internodal tracts, the AV node, the bundle of His, & the Purkinje system.
#Id: 3964
Conducting cells are specialized muscle cells which function to rapidly spread action potentials over the entire myocardium.
#Id: 3973
The action potential spreads throughout the myocardium in the following sequence: SA node  Atrial internodal tracts and atria  AV node  Bundle of His  Purkinje system  Ventricles
