APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The muscle layer of the heart is termed the myocardium and is made up of cardiomyocytes. The myocardium is found in the walls of all four chambers of the heart, though it is thicker in the ventricles and thinner in the atria.

Detailed explanation-2: -There are two major types of cardiac muscle cells: myocardial contractile cells and myocardial conducting cells.

Detailed explanation-3: -Cardiac muscle differs from skeletal muscle in that it exhibits rhythmic contractions and is not under voluntary control. The rhythmic contraction of cardiac muscle is regulated by the sinoatrial node of the heart, which serves as the heart’s pacemaker.

Detailed explanation-4: -The myocardium is mainly made up of two types of cells: cardiomyocytes and fibroblasts.
