20 kwi 2023 · In the anatomical position, the heart has five surfaces – each formed by the different chambers of the heart: Anterior (or sternocostal) – Right ventricle. Posterior (base of the pyramid) – Left atrium.
3 sie 2023 · The main reference points used for the surface projections of the heart are the borders of the sternum and costal cartilages, the clavicle and intercostal spaces. The latter favour sound transmission, facilitating clinical maneuvers such as percussion, auscultation and palpation to pinpoint the cardiac location.
This book covers the latest information on the anatomic features, underlying physiologic mechanisms, and treatments for diseases of the heart. Key chapters address animal models for cardiac research, cardiac mapping systems, heart-valve disease and genomics-based tools and technology.
11 sty 2021 · The sharp angle formed mainly by the right ventricle and occupying the lower heart border is the acute margin of the heart. The rounded obtuse margin of the heart is formed mainly by the left ventricle to the left of the sternocostal surface.
1 sty 2013 · The anatomical right border (the acute margin) separates the sternocostal and diaphragmatic surfaces. It is bounded in front by the thoracic wall represented by the posterior face of the sternum and the left sixth and seventh sternocostal articulations and the sixth left costal cartilage.
13 lut 2009 · Cardiac anatomy from right to left Axial (left) and coronal oblique (right) reconstructions of the heart, depicting the right atrium and its main contributing blood vessels: the coronary sinus (blue arrow) and superior and inferior vena cava.
The heart is placed in the mediastinum, between the lungs, and is encased by the pericardial sac, which has a posterior border near the spinal column and an anterior border near the sternum, with the diaphragmatic crurae on the inferior surface [1].
