Via the left and right coronary arteries.

Coronary Arteries
Oxygenated blood is brought to the myocardium by coronary arteries. These arteries are located all around he surface of the heart.

marginal branch posterior interventricular branch circumflex branch left coronary artery
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.
oxygenated blood oxygenated blood oxygenated blood
The heart pumps oxygenated blood only, all deoxygenated blood goes through veins so i think you are thinking about the aorta, which is the most important artery. And the myocardium is just the second layer of the heart, it isn't a part per se.
carry blood away from the heart to other parts of the body.ANSWER:Arteries usually carry oxygenated blood from heart to all the parts of the body whereas a coronary artery carries oxygenated blood and supplies it to the heart muscle-myocardium (for its functioning!) and that's where usually angina results as a result of artery thickening.Also the pulmonary artery is the only artery to carry de-oxygenated blood from the heart to the lungs for purification!!
The Right Coronary Artery supplies blood to the inferior myocardium
The myocardium (middle layer) has the bulk of the muscle which pumps blood from the ventricles.
Oxygenated blood is carried by all arteries but one which is the pulmonary artery
