Aug 3, 2023 · The surface projections of the heart represent points on the thoracic wall that map out the outline and valves of the heart. These include four borders (superior, right, inferior, left) and four valves (left atrioventricular, right atrioventricular, aortic, pulmonary).

Atlas of the Heart | Language shows us that naming an experience gives us the power of understanding and meaning. A quote from Atlas of the Heart by Brené Brown about how we cannot connect with someone unless we’re clear about where we end and they begin.
Aug 17, 2023 · The heart is located in the mediastinum within a region known as the cardiac box; the boundaries of which include: an imaginary line passing through the jugular notch superiorly, a parallel line passing through the xiphoid process inferiorly,

- Heart anatomy. The heart has five surfaces: base (posterior), diaphragmatic (inferior), sternocostal (anterior), and left and right pulmonary surfaces. It also has several margins: right, left, superior, and inferior
- Heart valves. Heart valves separate atria from ventricles, and ventricles from great vessels. The valves incorporate two or three leaflets (cusps) around the atrioventricular orifices and the roots of great vessels.
- Blood flow through the heart. The blood flow through the heart is quite logical. It happens with the heart cycle, which consists of the periodical contraction and relaxation of the atrial and ventricular myocardium (heart muscle tissue).
- Coronary circulation. The heart must also be supplied with oxygenated blood. This is done by the two coronary arteries: left and right. Heart muscles work constantly (thank goodness!)
Jun 4, 2018 · Torrent Guasp’s helical ventricular myocardial band (HVMB) defines this anatomy and its structure, and explains why the heart’s six dynamic actions of narrowing, shortening, lengthening, widening, twisting, and uncoiling happen.
It includes four rings that surround the openings between the atria and ventricles, and the openings to the pulmonary trunk and aorta, and serve as the point of attachment for the heart valves. The cardiac skeleton also provides an important boundary in the heart electrical conduction system.
