The myocardium does not have blood flow to the arm. The myocardium is the muscle of the heart and therefore only supplies blood to the heart.
The myocardium (middle layer) has the bulk of the muscle which pumps blood from the ventricles.
Blood
The myocardium is the thickest layer of the heart made of contractile muscles that pumps blood.
Oxygenated blood is brought to the myocardium by coronary arteries. These arteries are located all around he surface of the heart.
myocardium
The myocardium is the middle layer of the walls of the heart, made of cardiac muscle, that contracts to push out blood.
The coronary pathway takes blood to the heart.Related Information:Coronary arteries surround the heart and provided the muscles of the heart with blood.
The myocardium or heart muscle is nourished with oxygen-rich blood. The vessel that delivers the blood to the myocardium is called Coronary Arteries.
Aorta
myocardium
"Myo-" means muscle and "-cardium" means heart. So myocardium is heart muscle. It's the stuff that actually does the work of contracting the heart to pump blood around.
Myocardium is a type of muscle tissue. The reason why the myocardium receives its blood from coronary arteries and not from the cardiac chambers is because the blood from the cardiac chambers does not contain oxygen and nutrients.
