WebThe anterior and septal papillary muscles are connected by the moderator band. The septal papillary muscle itself is normally the least prominent and can often not be … The papillary muscles are muscles located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves (also known as the mitral and tricuspid valves) via the chordae tendineae and contract to prevent inversion or prolapse of these valves on systole (or ventricular contraction). The papillary … See more There are five total papillary muscles in the heart; three in the right ventricle and two in the left. The anterior, posterior, and septal papillary muscles of the right ventricle each attach via chordae tendineae to the tricuspid valve. … See more The papillary muscles of both the right and left ventricles begin to contract shortly before ventricular systole and maintain tension throughout.
