      Chordenae tendineae

    Correct Answer
    A. Papillary muscle
    Explanation
    The papillary muscle is a small muscle located in the walls of the ventricles of the heart. Its main function is to anchor the chordae tendineae, which are thin fibrous cords, to the valves of the heart. Specifically, the papillary muscles attach to the mitral valve (also known as the bicuspid valve) and the tricuspid valve. When the ventricles contract, the papillary muscles contract as well, pulling on the chordae tendineae and preventing the valves from being forced open in the wrong direction. Therefore, the papillary muscle is the correct answer in this case.

These structures help to prevent the walls of the ventricles from sticking together during contraction and aid in the proper flow of blood. Chordae tendineae are fibrous cords that attach the cusps of the heart valves to the papillary muscles, preventing the valves from inverting. Auricles are small, ear-like projections on the atria that increase the surface area for blood storage. Pectinate muscles are muscular ridges found on the inner wall of the atria.
