1 gru 2021 · Pericardium and epicardium. The normal pericardium is a sac that envelopes the heart, except at the 2 orifices, corresponding to the entrances and exits of the arterial trunks and veins surrounded by their pericardial reflections (Central Illustration, Figure 2) (31).
3 lis 2023 · The pericardium is the membrane that encloses the heart and the roots of the major heart vessels, consisting of an outer fibrous layer (fibrous pericardium) and an inner double serous membrane layer (serous pericardium).
2 lis 2023 · The pericardial cavity is a potential space between the opposing layers of the serous pericardium's parietal and visceral layer. This cavity has a fluid layer, that allows the heart to pulsate and move without friction. The fluid also serves to diminish surface tension and provide lubrication.
3 sie 2023 · 1. Layers (Walls) of the Heart. The heart is a hollow muscular organ whose wall is anatomically divided into three distinct layers; epicardium, myocardium, and endocardium. Epicardium. It is the outermost layer of the heart and the inner layer of the serous pericardium. It is composed of mesothelium tissues, fats, and connective tissues.

The anterior-most papillary muscle is connected to the interventricular septum by a distinctive band of cardiac muscle called the septomarginal trabecula (or moderator band). This structure is the only part of the electrical conduction system of the heart that is grossly visible.
