Mesocardium

The mesocardium is the middle layer of the heart wall, which is located between the endocardium and epicardium. This layer has a thickness of 3 to 5 mm and consists of connective tissue with small patches of smooth muscle.

The main function of the mesocardium is to provide strength and elasticity to the heart wall. It also plays an important role in maintaining normal heart rhythm and ventricular contractility.

The mesocardium has a high sensitivity to various hormonal and nervous signals, which allows it to regulate the functioning of the heart in accordance with the changing needs of the body. For example, when the level of adrenaline or norepinephrine in the blood increases, the mesocardium stimulates heart contractions and increases
