-cardium Also -cardial.
Tissue related to the heart.
[Greek kardia, heart.]
The oldest such term, the model for the others, is pericardium (Greek peri, around), the membrane enclosing the heart. Other examples are epicardium (Greek epi, upon, near to) a membrane that forms the innermost layer of the pericardium, attached to the muscles of the wall of the heart; endocardium (Greek endon, within), the thin, smooth membrane which lines the inside of the chambers of the heart and forms the surface of the valves; and myocardium (Greek mus, mu-, muscle), the muscular tissue of the heart. Associated adjectives are formed in -cardial (endocardial, myocardial).
