myocardium. [mÄ«â²Åkaerâ²ÅkÃ¤rÂ·dÄ]. Ém: Etymology, gk, mys, muscle, kardia. heart a thick contractile middle layer of uniquely constructed and arranged muscle cells that forms the bulk of the heart. Wall the myocardium contains a minimum of other, tissue except blood, vessels and is covered interiorly by the. endocardium
Surrounding the heart is a fibrous sac called the pericardium. This sac protects the heart, and is actually composed of two layers: an inner visceral one and an outer parietal one. When the heart moves (i.e. when the heart beats), these two layers move with it.For this to happen, it is important that there is no friction between the two layers of the pericardium, which is why pericardial fluid lines the inner space between the them.Much like oil in an engine, the pericardial fluid makes for less friction between the inner and outer layer of the pericardium.he pericardial cavity or sac is the potential space between the parietal and visceral layers of serous pericardium. In other words, two different layers of cardiac tissue.
