Facets:
Source sentences:
text: and then the ventricles to contract - contractile cells line the the surrounding of the heart, but the heart is separated by thin membrane that prevents action potentials happening in the atria to initiate action potentials in the ventricles (action potentials only have one area they can travel)
text: His constitute the only electrical connection between the atria and ventricles - except for this pathway, the atria are completely separated from the ventricles by a layer of nonconducting connective tissue (prevents action potentials happening in the atria to initiate action potentials in the ventricles - action potentials only have one area they can travel)
