CHORDAE TENDINEAE are cords within the atrioventricular valves of the heart (Tricsupid Valve and Bicuspid/Mitral Valve) that resemble tiny tendons that attach the papillary muscle to the cusps of the valve, thereby helping the valve to prevent backflow of blood back into the atrial chambers. . . #instituteofhumananatomy #anatomy #anatomylab #anatomyclass #learnanatomy #learn #learning #physiology #physiologyclass #biology #biologyclass #science #scienceclass #cadaver #cadaverlab #cadavers #heart
