What is the myocardium?


The Red Tissue is the Myocardium

The myocardium is the middle muscular layer of the heart.  It lays between the outer epicardium layer and the inner endocardium layer.

The Myocardium is also called cardiac muscle. Heart Muscles are involuntary muscles that are controlled by the autonomic nervous system. The muscle is responsible for the smooth rhythmic contractions that pump blood throughout the body. When someone is said to have had a heart attack, it is the myocardium that has been affected.
