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. The myocardium is made up of two types of cells: cardiac muscle cells (also called heart muscle cells,cardiomyocytes, cardiac myocytes, or cardiac rahbdomy...
What is cardiac muscle? It is important to understand the definition of cardiac muscles. Basically, cardiac muscles are the involuntary, striated musclesthat are made up of cardiac muscle cells or cardiomyocytes. Cardiac muscles are one of the three types of vertebrate muscles (the other two being, skeletal muscles and smooth muscles). Cardiac musc...
To understand the circulatory system, it is important to understand what is the function of the myocardium. The primary function of the cardiac muscles isto stimulate contractions and relaxation in the heart. The contraction action results in the pumping of the blood from the ventricles to the whole body while the relaxation action of the cardiac m...
So, what actually happens in cardiac muscles when your heart beats? The action potential or nerve impulse stimulates the sarcoplasmic reticulum resulting in the release of calcium ions (Ca2+) into the cytoplasm. The cytoplasmic Ca2+ ions induce the troponin to release tropomyosin. Released Tropomyosin alters its position thereby allowing myosin to ...
Myocardial dysfunction can be categorized into two types: primary (due to genetic cause) and secondary myocardial diseases (mostly acquired causes but maybe precipitated due to genetic reasons).
The heart is the central pumping organ of the body. Contraction and relaxation of the heart result in the pumping of blood throughout the body. For the normal functioning of the body, the cells and tissue need a sufficient amount of oxygen which is supplied by the circulating blood. Cardiac muscles or the myocardium are responsible for the rhythmic...
