The endocardium is the innermost layer of the heart wall.
Most of the middle layer in the heart wall is composed of cardiac muscle cells. Cardiac muscle cells are also known as cardiomyocytes.
The heart wall is richly supplied with blood vessels, and it is composed of three layers: the epicardium, the myocardium, and the endocardium.First layer--Epicardium is the visceral layer of the serous pericardium. It is often infiltrated with fat, especially in older people.Middle layer--Myocardium ("muscle heart") is composed mainly of cardiac muscle and forms the bulk of the heart. It is the layer that contracts.Third layer--Endocardium ("inside the heart") is a glistening white sheet of endothelium (squamous epithelium) resting on a thin connective tissue layer. Located on the innermyocarial surface, it lines the heart chambers and covers the fibrous skeleton of the valves. Endocardium is continuous with the endothelial linings of the blood vessels leaving and entering 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.
Yes. For future refference myo as a prefix generally means it has something to do with muscle contraction. Cardi odviously means is has something to do with the heart.
No, the deoxygenated blood enters and leaves the heart through the right side and the oxygenated blood enters and leaves the heart through the left side. Both sides of the heart are separated by a wall called a septum. The wall between the left and right atria is the interatrial septum and the wall between the left and right ventricles is the interventricular septum.
The layers of the HEART {outermost-innermost} 1. Epicardium {This is the outer layer is also known as VISCERAL PERICARDIUM and contains fat, which helps to cushion the heart} 2. Myocardium {This middle layer is the thickest layer of the wall and is made primarily of cardiac muscle} Endocardium {This innermost layer is thin and very smooth, and stretches as the heart pumps blood}
It is the innermost layer of the fruit wall called the endocarp.

The thick layer of the heart wall that contains contractile cardiac muscle tissue is the myocardium. The layer of the heart wall synonymous with the visceral layer of the serous pericardium is epicardium.
Tunica Intima is the innermost layer of the wall of the artery. The wall is consist of simple squamous epithelium which is called endothelium.

innermost layer
The body wall consists of three main layers: the outermost layer is the integumentary system (skin), followed by the connective tissue layer (dermis), and the innermost layer is the muscular layer (muscles). These layers work together to provide protection, support, and movement for the body.
The endocardium is the innermost layer of the heart wall, composed of endothelial cells and connective tissue. It is continuous with the inner lining of blood vessels and helps regulate blood flow and prevent clotting within the heart chambers. The endocardium also provides a smooth surface for efficient heart function.

The endocardium is the layer of the heart wall that is made up of endothelium overlying connective tissue. This layer lines the interior of the heart chambers and valves, providing a smooth surface for blood flow.
Most of the middle layer in the heart wall is composed of cardiac muscle cells. Cardiac muscle cells are also known as cardiomyocytes.
