    Jul 26, 2024 · The heart wall is composed of connective tissue, endothelium, and cardiac muscle. It is the cardiac muscle that enables the heart to contract and allows for the synchronization of the heartbeat. The three heart wall is divided into three layers: epicardium, myocardium, and endocardium. Epicardium: the outer protective layer of the heart.

    Your heart is in the front of your chest. It sits slightly behind and to the left of your sternum (breastbone), which is in the middle of your chest. Your heart is slightly on the left side of your body. It sits between your right and left lungs. The left lung is slightly smaller to make room for the heart in your left chest. Your rib cage protects...

    Your heart looks a little bit like an upside-down pyramid with rounded edges. Large blood vessels go into and out of your heart to bring blood into and away from your heart. They connect your heart to the rest of your body, which it supplies with blood and oxygen.

    • Location of the Heart. The human heart is located within the thoracic cavity, medially between the lungs in the space known as the mediastinum. Figure 19.2 shows the position of the heart within the thoracic cavity.
    • Shape and Size of the Heart. The shape of the heart is similar to a pinecone, rather broad at the superior surface and tapering to the apex (see Figure 19.2).
    • Chambers and Circulation through the Heart. The human heart consists of four chambers: The left side and the right side each have one atrium and one ventricle.
    • Membranes, Surface Features, and Layers. Our exploration of more in-depth heart structures begins by examining the membrane that surrounds the heart, the prominent surface features of the heart, and the layers that form the wall of the heart.

    Layers. The wall of the heart is composed of three layers of unequal thickness. From superficial to deep, these are the epicardium, the myocardium and the endocardium (see Figure 6.1.4). The outermost layer of the wall of the heart is also the innermost layer of the pericardium, the epicardium, or the visceral pericardium discussed earlier.

    Jan 4, 2024 · In addition to the connective tissue and fat, the epicardium is lined by on its outer surface by simple squamous epithelial cells. The heart wall itself can be divided into three distinct layers: the endocardium, myocardium, and epicardium. In this article, we shall look at the anatomy and clinical relevance of these layers.

    The heart is composed of three layers: the epicardium (outer layer) which prevents excess expansion or movement of the heart, the myocardium (middle layer) which initiates contractions driving the cardiac cycle, and the endocardium (inner layer) that lines the cavities and valves. The heart contains two upper chambers called atria and two lower ...
