" /> papillary muscle of heart - CISMeF





Preferred Label : papillary muscle of heart;

Uberon definition : one of the group of myocardial bundles which terminate in the chordae tendineae that attach to the cusps of the atrioventricular valves; each ventricle has an anterior and a posterior papillary muscle; the right ventricle sometimes has a septal papillary muscle;

Uberon synonym : ventricular papillary muscle; papillary muscle of ventricle; ventricule papillary muscle; papillary muscle;

Uberon Function note : These muscles contract to tighten the chordae tendineae, which in turn prevent inversion. This occurs in response to pressure gradients. Instead they brace the valves against the high pressure, preventing regurgitation of ventricular blood back into the atrial cavities.[Wikipedia:Papillary_muscle];

Uberon Homology note : On the internal or parietal surface of the left ventricle in man and in mammals are two papillary muscles, which are almost identical and well developed.[well established][VHOG];
