The heart wall is comprised of three layers, the epicardium (outer), myocardium (middle), and endocardium (inner). These tissue layers are highly specialized and perform different functions.
Aug 4, 2023 · 1. Epicardium (Outermost Layer of Heart) The epicardium is the outermost layer of the heart wall made up of mesothelium, fats, and connective tissues. It forms the inner serous layer of the pericardium; hence, it is also known as the visceral serous pericardium.
Nov 3, 2023 · The myocardium is functionally the main constituent of the heart and the thickest layer of all three heart layers. It is a muscle layer that enables heart contractions. Histologically, the myocardium is comprised of cardiomyocytes .
The wall of the heart is composed of three layers of unequal thickness. From superficial to deep, these are the epicardium, the myocardium, and the endocardium (see Figure 19.5 ). The outermost layer of the wall of the heart is also the innermost layer of the pericardium, the epicardium, or the visceral pericardium discussed earlier.
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.
