outer layer of the heart is called?????
Answers
Answer:
The epicardium is continuous with the visceral layer of the serous parietal pericardium.
Between the epicardium and the myocardium are the coronary blood vessels. These vessels are usually surrounded by fat.
The myocardium is the muscle of the heart. It is involuntary striated cardiac muscle, made up of a whole network of dividing and recombining fibres. This is the part of the heart that allows for contraction. The amount of myocardium is different for each of the chambers, depending on the amount of force needed in the contraction - for example, there is a proportionally large amount of myocardium in the walls of the ventricles (particularly the left). The myocardium contains a large number of mitochondria, providing energy for the heart muscle.
The endocardium forms the inner lining of the heart, and the flaps which form the valves of the heart.
