The middle layer of the heart wall is the myocardium, which is the cardiac muscle â a layer of involuntary striated muscle tissue surrounded by a framework of collagen. The myocardium is also supplied with blood vessels, and nerve fibers by way of the epicardium that help to regulate the heart rate.he heart is a muscular organ in humans and other animals, which pumps blood through the blood vessels of the circulatory system.
