Fibrous pericardium

A transverse section of the thorax, showing the contents of the middle and the posterior mediastinum. The pleural and pericardial cavities are exaggerated since normally there is no space between parietal and visceral pleura and between pericardium and heart.
Latin	pericardium fibrosum

The fibrous pericardium is the most superficial layer of the pericardium in the heart. It is made up of dense connective tissue, a loose connective tissue ¹ which acts to protect the heart, anchoring it to the surrounding walls, and preventing it from overfilling with blood. It is continuous with the outer adventitial layer of the neighboring great blood vessels.

Anatomy of torso, cardiovascular system: heart (TA A12.1, TH H3.09.01, GA 5.524)

General

Surface	base · apex · grooves (coronary/atrioventricular, interatrial, anterior interventricula, posterior interventricular) · surfaces (sternocostal, diaphragmatic) · borders (right, left) · Openings of smallest cardiac veins

Internal	atria (interatrial septum, musculi pectinati, sulcus terminalis) · ventricles (interventricular septum, trabeculae carneae, chordae tendineae, papillary muscle) · valves · cusps · Atrioventricular septum cardiac skeleton Intervenous tubercle

Chambers

Right heart	(venae cavae, coronary sinus) → right atrium (atrial appendage, fossa ovalis, limbus of fossa ovalis, crista terminalis, valve of inferior vena cava, valve of coronary sinus) → tricuspid valve → right ventricle (conus arteriosus, moderator band/septomarginal trabecula) → pulmonary valve → (pulmonary artery and pulmonary circulation)

Left heart	(pulmonary veins) → left atrium (atrial appendage) → mitral valve → left ventricle → aortic valve (aortic sinus) → (aorta and systemic circulation)

Layers

Endocardium	Heart valves

Myocardium	Conduction system: Cardiac pacemaker · SA node · AV node · bundle of His · Purkinje fibers

Pericardial cavity	Pericardial sinus

Pericardium	fibrous pericardium (Sternopericardiac ligaments) · serous pericardium (epicardium/visceral layer) · Fold of the left vena cava
