NEW！心臓周囲の構造
| 特長 | 心のうから心臓を取りのぞくことで、心臓を取り巻く周囲の臓器と心臓の関係を観察することができます Product information "Pericardial space" In this specimen the heart itself has been removed to demonstrate the reflections of parietal peritoneum and the orientation of the heart relative to other structures, including the diaphragm (diaphragmatic surface) and the lungs (left and right pulmonary surfaces). The pericardium is the multilayered fibroserous sac that encloses the heart and is continuous with the serous visceral pericardium (epicardium) of the heart itself. In normal anatomical position, the boundaries of the parietal pericardium are also the boundaries of the middle mediastinum (what we call coterminous). The internal surface of the parietal peritoneum has been false coloured to aid in identifying the regions of the heart that are normally positioned in these parts of the middle mediastinum. The base of the heart is roughly rectangular and projects superiorly and posteriorly (anterior to the hilum of the lungs). It can be seen on the model as the most posterior surface left by the impression of the heart. It is formed by the left atrium (pink) (and to a lesser extent the right atrium [blue-green]) and the proximal parts of the great vessels (red and blue) as they enter and leave the heart. This is also the ‘fixed’ region of the heart, anchoring the heart through the origins of the great vessels where the visceral and parietal serous pericardium are reflected and continuous. The transverse pericardial sinus (clinically relevant for some cardiac surgical procedures) is visible between the pulmonary arteries (red) and the bases of the superior vena cava, pulmonary trunk, and ascending aorta. Inferior to the pulmonary veins, the depressed region formed by the left atrium and left ventricle is termed the oblique pericardial sinus. From the base, the heart projects anteriorly, inferiorly and towards the left side of the thorax. The most inferior and lateral point is the apex. The apex is formed by the inferolateral part of the left ventricle (yellow) and is normally found in the left fifth intercostal space along the midclavicular line. Within the mediastinum, the heart rests on the diaphragmatic surface, consisting mainly of left ventricle (and to a lesser extent the right ventricle [light green]). This is the most inferior aspect of the heart and is separated from the base (the posterior surface) by the coronary sinus. It extends from the base of the heart to its apex. On the model it is the area that is just anterior and inferior to the ostium of the inferior vena cava. The pulmonary surfaces are the broad and convex right and left lateral sides of the heart. The left pulmonary surface reflects onto the left lung and consists mainly of the left ventricle. The right pulmonary surface reflects onto the right lung and consists of the right atrium. The heart also has an anterior surface that consists mostly of the right ventricle with some right atrium on the right and left ventricle on the left. In this model this surface cannot be appreciated as it has been dissected deep to the anterior surface. The portion of the pericardium that can be seen being reflected to either side would have covered, in part the anterior surface before they were reflected. |
