Papillary Muscle

Papillary muscles of the human heart are five in number. They are anterior, posterior, and septal of the right ventricle and anterolateral and posteromedial of the left ventricle. The former three muscles attach to the tricuspid valve, and the latter two muscles attach to the mitral valve. They prevent ventricular blood flow into the atria. Myocardial infarction leads to the rupture of these muscles.
