Answer:
Option-D
Explanation:
The myocardial cells form the cardiac muscle present in the heart. The heart receives its signal from the autonomic nervous system but not all the cells receive the signals.
The SV and AV node present in the upper heart produces the potential for the contraction. The action potential gets transferred through the cell and finally reach the lower ventricle through Purkinje fibres.
This allows the contraction of both the ventricles simultaneously and sows that the heart cells contract simultaneously.
Thus, Option-D is the correct answer.
