Comprehensive description of boundries and contents of the middle mediastinum, layers of the pericardium, clinical significance of the pericardial cavity, cardiac sinuses, orientation, borders, and surface features of the heart, including pathway and tissues the coronary arteries and cardiac veins supply/drain, clinical relevance of coronary artery occlusion.
The human heart is situated to the left of the chest and is enclosed within a fluid-filled cavity described as the pericardial cavity. The walls and lining of the pericardial cavity are made up of a membrane known as the pericardium. The pericardium is a fibre membrane found as an external covering around the heart.
