Most of the myocardium is composed of cardiac myocytes.
The portion of the nervous system that is most closely associated with the contraction of the cardiac muscle is the autonomic nervous system.
They occur in the tropical convergence zone
Most accidents in urban areas occur at intersections.
No, most cardiac muscles are not directly controlled by the nervous system. The cardiac muscles have their own intrinsic pacemaker called the sinoatrial (SA) node that generates electrical impulses and coordinates the contraction of the heart. While the nervous system can influence the rate and strength of the heart's contractions, it does not have direct control over the cardiac muscles.

Cardiac arrest occurs when the heart stops beating (or arrests). When a myocardial infarction (MI) occurs a portion of the heart either dies or becomes ischemic. Usually arrest wouldn't be due to an MI but if an MI was big enough it would initiate an arrhythmia called fibrillation and the heart would stop pumping blood. This is also called sudden cardiac death. SCD can occur without an MI as well.
