The CCIM Institute, headquartered in Chicago and an affiliate of the National Association of REALTORSÂ®, awards the CCIM designation to individuals who complete a process based both on commercial and investment real estate theory and practice. Weâll review this process in a moment.
The myocardium is the middle muscular layer of the heart's walls and it functions by providing a scaffolding for the heart chambers, assisting in contraction and relaxation of the cardiac walls so that blood can pass between the chambers and electrostimulation conduction through its own tissues and into the epicardium.
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.ardiomyocytes, like all other cells, need to be supplied with oxygen, nutrients and a way of removing metabolic wastes. This is achieved by the coronary circulation. The coronary circulation cycles in peaks and troughs correlating to the heart muscle's relaxation or contraction.
