Myocardium: definition, structure and function | Kenhub The heart is a muscular organ comprised of three layers that include the endocardium, myocardium, and epicardium The myocardium is the middle muscular layer of the heart
The 3 Layers of the Heart Wall - ThoughtCo 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
Cardiac muscle - Wikipedia Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissues, the others being skeletal muscle and smooth muscle It is an involuntary, striated muscle that constitutes the main tissue of the wall of the heart
Myocardium – Definition, Structure, Functions - Biology Notes Online The myocardium is the thick, muscular middle layer of the heart wall, located between the epicardium and endocardium It is primarily composed of cardiac muscle cells (cardiomyocytes) that enable the heart to contract and pump blood throughout the body
Understanding The Myocardium: Heart Muscle Explained The myocardium, also known as cardiac muscle, is the thick middle layer of the heart, which is responsible for the heart's contraction and relaxation It is one of three types of vertebrate muscle tissues, the other two being skeletal muscle and smooth muscle
Cardiac muscle tissue: Definition, function, and structure Cardiac muscle tissue, or myocardium, is a type of muscle tissue that forms the heart It contracts and releases involuntarily and keeps the heart pumping blood around the body
Myocardium - an overview | ScienceDirect Topics The middle layer of the heart, the myocardium, forms the bulk of the heart wall and comprises mostly striated, involuntary cardiac muscle embedded within a dynamic extracellular matrix that plays a pivotal role in the three-dimensional organization and mechanical performance of the heart
Myocardium Definition and Examples - Biology Online Dictionary What is the myocardium of the heart? It is the muscular middle layer of the heart that is sandwiched between the epicardium and endocardium Sometimes it is referred to as the mass of the heart
