Muscle, Cardiac

Muscle, cardiac - see Myocardium.

The myocardium is the muscle tissue that makes up the heart. The myocardium is responsible for the contraction of the heart and provides blood circulation throughout the body. Myocardial contractions occur rhythmically, ensuring continuous heart function throughout life. Damage or disease to the myocardium can impair the functioning of the heart and lead to heart failure. Therefore, myocardial health is essential for the normal functioning of the cardiovascular system.
