   The heart is composed of three layers: the epicardium (outer layer) which prevents excess expansion or movement of the heart, the myocardium (middle layer) which initiates contractions driving the cardiac cycle, and the endocardium (inner layer) that lines the cavities and valves.

   • Epicardium. Epicardium (epi-cardium) is the outer layer of the heart wall. It is also known as visceral pericardium as it forms the inner layer of the pericardium.
   • Myocardium. Myocardium (myo-cardium) is the middle layer of the heart wall. It is composed of cardiac muscle fibers, which enable heart contractions. The myocardium is the thickest layer of the heart wall, with its thickness varying in different parts of the heart.
   • Endocardium. Endocardium (endo-cardium) is the thin inner layer of the heart wall. This layer lines the inner heart chambers, covers heart valves, and is continuous with the endothelium of large blood vessels.

   Oct 30, 2023 · The heart contains three basic layers similar to those seen in arteries and veins. The outermost layer is the epicardium, which is derived from the proepicardium (from the septum transversum). The middle layer is the myocardium, and the innermost layer is the endocardium, which originated from mesothelial cells of the outflow tract.

   Sep 14, 2021 · Our exploration of more in-depth heart structures begins by examining the membrane that surrounds the heart, the prominent surface features of the heart, and the layers that form the wall of the heart. Each of these components plays its own unique role in terms of function.

   What are the 3 layers of the heart?

   • Histologically, the heart is made of three layers of tissue: epicardium, myocardium, and endocardium. The epicardium is the outermost layer of the heart. It is actually the visceral layer of the serous pericardium, which adheres to the myocardium of the heart. Histologically, it is made of mesothelial cells, the same as the parietal pericardium.

   What is the outer layer of the heart called?

   • Epicardium: the outer protective layer of the heart. Myocardium: muscular middle layer wall of the heart. Endocardium: the inner layer of the heart. Epicardium (epi- cardium) is the outer layer of the heart wall. It is also known as visceral pericardium as it forms the inner layer of the pericardium.

   What are the walls of the heart composed of?

   • The walls of the heart are composed of an outer epicardium, a thick myocardium, and an inner lining layer of endocardium. The human heart consists of a pair of atria, which receive blood and pump it into a pair of ventricles, which pump blood into the vessels.

   Which layer of the heart is in direct contact with the myocardium?

   • The inner layer of the epicardium is in direct contact with the myocardium. Myocardium (myo-cardium) is the middle layer of the heart wall. It is composed of cardiac muscle fibers, which enable heart contractions. The myocardium is the thickest layer of the heart wall, with its thickness varying in different parts of the heart.

   What are the two layers of the endocardium?

   • The endocardium has two layers. The inner layer lines the heart chambers and is made of endothelial cells. Superiorly, is the second layer: a subendocardial connective tissue which is continuous with the connective tissue of the myocardium. Branches of the heart’s conduction system are immersed into the subendocardial layer.
