Epicardium: is the line on the exterior of the heart, ie the portion interacting with other organs.
Myocardium: is the layer in which the muscle resides
Epicardium: is the inner lining on the heart. ie the portion in contact with the blood being pumped

Where is the myocardium located in the heart?
The myocardium is located between the endocardium and the visceral layer of the serous membrane (epicardium) of the heart.
What are segments of the walls of the Heart?
The walls of the heart are made up of three layers of cardiac muscle called epicardium, myocardium, and endocardium. These muscle layers are made up of different things. The outermost layer is the thin epicardium muscular covering of the heart. This layer is made up of mostly connective tissue and fat. The inside layer is a thick layer of muscle called the myocardium which is made up of cardiomyocytes, excitable cells that can propagate quickly and can spread their action potentials to surrounding cells. Each cell can physically contract to make the heart muscle shorten. This is the largest layer and accounts for about 80% of the heart. The inner lining muscle layer of the heart is a smooth membrane called endocardium. It is made up of endothelial cells just like the linings of the blood vessels.
What is The inner surface of the heart lined with?
The endothelium is the thin layer of cells that line the interior surface of blood vessels, forming an interface between circulating blood in the lumen and the rest of the vessel wall.The endocardium is the innermost layer of tissue that lines the chambers of the heart.
What is the difference between coronary arteries and vessels?
When people use the word vessel in relation to the cardiovascular system, they usually are referring to blood vessels like arteries, veins, or capillaries. Coronary arteries are specific blood vessels that carry oxygenated blood to the muscles (myocardium) of the heart.
What is the difference between lanthanides and actinides?
Wht is the difference between Lanthanides and Actinides?
What is the meaning of myocardium?
The main substance of the muscular wall of the heart inclosed between the epicardium and endocardium.
Where is the myocardium located in the heart?
The myocardium is located between the endocardium and the visceral layer of the serous membrane (epicardium) of the heart.
Which term refers to the membrane between the outermost and innermost part of the heart?
The tissue of the heart is composed of three major layers: The outer most is the Epicardium. "Epi" refers to "outside" The inner most layer is the Endocardium. "Endo" refering to "inside" The layer in between is called the Myocardium. It is the thickest layer and is composed of cardiac muscle. Thus its name, as "myo" is a prefix meaning "muscle".
Name the muscle layer of the heart wall?
The heart is a main organ . to protect it self from the external effects through cardiac layers which are number in 2 the space between them filled with pericardiacfluid .
What are the layers of the heart wall from superficial to deep?
The heart consists of three tissue layers: endocardium, myocardium, and pericardium. The endocardium, the innermost layer, lines the hearts chambers and is bathed in blood. The myocardium is the thick middle layer of the heart. Its cells are unique in that they physically resemble skeletal muscle but have electrical properties similar to smooth muscle. These cells also contain specialized structures that help to rapidly conduct electrical impulses from one muscle cell to another, enabling the heart to contract. The pericardium is a protective sac surrounding the heart, which consists of two parts: the inner serous pericardium and the outer fibrous pericardium. The serous pericardium has two layers--the visceral and the parietal. The visceral pericardium, also called the epicardium, is the inner layer, in contact with the heart muscle itself. The parietal pericardium is the outer, fibrous layer. In the pericardial cavity, between these two layers, is about 25 milliliters of pericardial fluid, a lubricant that reduces friction as the heart beats and changes position. The fibrous pericardium encases the serous pericardium. It is made of dense connective tissue and is attached to both the diaphragm and the base of the great vessels.
What is the difference between stunned myocardium and hibernating myocardium?

What is the difference between the Visceral Pericardium and the Epicardium?
They are the same.
The outer covering of the heart?
The heart is encased in two protective layers. The outer layer -- the pericardium -- covers the heart. It folds in on itself at the aorta forming the epicardium of the heart. Between these layers is a small amount of fluid (10-50 ml) that affords the layers a non-stick surface.
What are segments of the walls of the Heart?
The walls of the heart are made up of three layers of cardiac muscle called epicardium, myocardium, and endocardium. These muscle layers are made up of different things. The outermost layer is the thin epicardium muscular covering of the heart. This layer is made up of mostly connective tissue and fat.

The inner lining muscle layer of the heart is a smooth membrane called endocardium. It is made up of endothelial cells just like the linings of the blood vessels.
What attaches cardiac muscle fibers together?
The myocardial cells are connected through tight junctions and gap junctions between the cell membranes of adjacent cells. The myocardium as a whole is covered by the pericardium on the outside and the endocardium on the inside.
Space between the epicardium and the parietal pericardium?
pericardial cavity
What is the space between the epicardium and the parietal pericardium?
The pericardial sac.
