Tendons that connect the cardiac valves to the papillary musclesSmall muscles that attach to the inner wall of the ventricles and to the chordae tendaneae (which in turn are connected to the heart’s valves).

The valves are composed of similar components: leaflets; annulus – a fibrous ring that encircles the valve; and chordae tendaneae – fibrous ligaments that connect to the papillary muscles. The papillary muscles flex when the ventriclesThe larger chambers of the heart (3 times the volume and muscle thickness than the atria), responsible for the pumping of blood to the lungs and the rest of the body. contract to stabilize the AV valves. Note that an MI may weaken papillary muscles or rupture the chordae tendaneae, resulting in a heart murmur.
