11 sty 2021 · Inferior to the thymus, a fibrous pericardial sac encloses the mass of the heart. The sac has cuff-like attachments around the adventitia of the great arteries and veins as they enter or emerge from the heart. The pericardial cavity is contained between the double-layered serous pericardium.

27 lis 2024 · Explore the anatomy and core functions of the heart with Innerbody's interactive 3D model. The heart is a muscular organ about the size of a closed fist that functions as the body's circulatory pump.
The heart has the shape of a pyramid, with its apex pointing towards the left nipple while its base forms the posterior surface of the heart. Other surfaces are the anterior, inferior (or diaphragmatic), and two pulmonary surfaces facing the lungs.
The heart is a conical hollow muscular organ situated in the middle mediastinum and is enclosed within the pericardium. It is positioned posteriorly to the body of the sternum with one-third situated on the right and two-thirds on the left of the midline. The heart measures 12 x 8.5 x 6 cm and weighs ~310 g (males) and ~255 g (females).

3 lis 2023 · Definition, function and anatomy of the myocardium. This article will discuss the layers of the heart (the epicardium, the myocardium and the endocardium) and any clinical relations pertaining to them. In the same way that vehicles have their fuel pumps, our body has the heart.
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.
