Where is the myocardium found?
the heart wall
The cardiac muscle (myocardium) forms a thick middle layer between the outer layer of the heart wall (the pericardium) and the inner layer (the endocardium), with blood supplied via the coronary circulation.
What does the endocardium protect the myocardium from?
The endocardium is the innermost layer of tissue that lines the chambers of the heart. Its cells are embryologically and biologically similar to the endothelial cells that line blood vessels. The endocardium also provides protection to the valves and heart chambers….

What type of tissue is myocardium?
Cardiac muscle tissue, or myocardium, is a specialized type of muscle tissue that forms the heart. This muscle tissue, which contracts and releases involuntarily, is responsible for keeping the heart pumping blood around the body.
What is another name for epicardium?
The inner part of the pericardium that closely envelops the heart is, as stated, the epicardium; it is also called the visceral pericardium.
What is the main function of the myocardium?
Function of the Myocardium Myocardium stimulates heart contractions to pump blood from the ventricles and relaxes the heart to allow the atria to receive blood. These contractions produce what is known as a heart beat. The beating of the heart drives the cardiac cycle which pumps blood to cells and tissues of the body.
What is the difference between epicardium and pericardium?
As nouns the difference between pericardium and epicardium is that pericardium is (anatomy|cardiology) a serous membrane that surrounds the heart allowing it to contract while epicardium is (anatomy) the layer of tissue between the pericardium and the heart.
What type of tissue is the epicardium made of?
The epicardium, or the innermost layer of the pericardium, is the outermost layer of the heart itself. It is composed of mesothelial cells, fat, and connective tissue. It is adjacent to the myocardium, the middle muscular layer. The innermost layer is referred to as the endocardium.
What are the three layers of the heart?

What is the outermost layer of the heart?
– Epicardium: the outer protective layer of the heart. – Myocardium: muscular middle layer wall of the heart. – Endocardium: the inner layer of the heart.
What is the function of the myocardium?
The primary function of the myocardium (heart) is to generate the force necessary (through contraction)to circulate blood through the body. Blood is pumped by the heart and circulated through through the body using specific circuits to transport oxygen, carbon dioxide, waste within the body, and to deliver blood to the lungs for gas exchange.
What does the epicardium do?
It keeps your heart fixed in place within your chest cavity.
