What term refers to the heart muscle?

Explanation:
The heart muscle is the myocardium. It’s the thick muscular layer that contracts to pump blood through the body. This layer sits between the inner lining of the heart chambers (the endocardium) and the outer surface (the epicardium), with the pericardium forming the protective sac around the whole heart. The myocardium’s cardiac muscle cells are connected by intercalated discs, which allows the heart to beat in a coordinated, rhythmic way. If the heart muscle is affected by disease, you might hear terms like myocarditis or cardiomyopathy.
