Translations
pericardium
pericardium: see heartheart,
muscular organ that pumps blood to all parts of the body. The rhythmic beating of the heart is a ceaseless activity, lasting from before birth to the end of life. Anatomy and Function
The human heart is a pear-shaped structure about the size of a fist.

The pericardium is an isolated part of the secondary body cavity, the coelom. It consists of two layers: an external, parietal layer—the pericardium proper—and an internal, visceral layer—the epicardium. The pericardium proper consists, in turn, of an internal, serous layer and an external, fibrous layer. The epicardium, being an external membrane of the heart, directly covers and is fused to the heart muscle (myocardium). In the region where large blood vessels enter and leave the heart, the epicardium is turned back and is continuous with the pericardium proper. Between the pericardium layers is a slitlike cavity containing a small quantity of transparent pale-yellow serous fluid. The pericardium contains blood vessels, lymphatics, and numerous nerve endings and is surrounded by areolar connective tissue. It has many receptors, whose stimulation causes hemodynamic and respiratory changes. pericardium[‚per·ə′kärd·ē·əm] (anatomy) The membranous sac that envelops the heart; it contains 5-20 grams of clear serous fluid. pericardium the membranous sac enclosing the heart pericardium

Called also epicardium.per·i·car·di·um, pl. per·i·car·di·a (per'i-kar'dē-ŭm, -ă), [TA] The fibroserous membrane, consisting of mesothelium and submesothelial connective tissue, covering the heart and beginning of the great vessels. It is a closed sac having two layers: the visceral layer (epicardium), immediately surrounding and applied to all the heart's surfaces, and the outer parietal layer, forming the sac, composed of strong fibrous tissue (fibrous pericardium [TA]) lined with a serous membrane (serous pericardium [TA]). The phrenic nerves pass to the diaphragm through the anterior pericardium and divide the pericardium into antephrenic and retrophrenic portions; the pulmonary hilum divides both of these portions into suprahilar, hilar, and infrahilar portions.
