The chordae tendineae are also known as the "heart strings." They are fibrous cords that connect the papillary muscles to the atrioventricular valves (mitral and tricuspid valves) in the heart. These structures play a crucial role in preventing the valves from inverting or prolapsing during ventricular contraction, ensuring proper blood flow through the heart.
