Study Notes
Layers of the Heart
- Epicardium: The outermost layer of the heart, also referred to as the visceral layer of the pericardium, which provides a protective covering.
- Myocardium: The middle and thickest layer, composed of cardiac muscle tissue responsible for the heart's pumping action and contraction.
- Endocardium: The innermost layer that lines the heart chambers and valves, ensuring a smooth surface for blood flow.
Blood Supply to the Heart
- Coronary Arteries: Arteries that supply blood specifically to the heart muscle, essential for delivering oxygen and nutrients.
- Coronary Occlusion: A medical condition where there is a blockage that disrupts blood flow to the myocardium, potentially leading to serious complications.
Related Terms
- Coron/o: A prefix meaning "crown," often associated with the heart and its vascular system.
- Ischemia: A state of reduced blood supply to an area, which can impair function and lead to damage if prolonged.
- Necrosis: The death of tissue, which can occur due to various factors including lack of blood supply.
- Infarct/Infarction: A localized area of necrosis resulting from interrupted blood supply, commonly associated with heart attacks.
