Chordae Tendineae Picture
Chordae Tendineae are thread-like bands of fibrous tissue which attach on one end to
the edges of the tricuspid and mitral valves of the heart and on the other end to the
papillary muscles, small muscles within the heart that serve to anchor the valves.
The chordae tendineae, or heart strings, are cord-like tendons that connect
the papillary muscles to the tricuspid valve and the mitral valve in the heart.
Chordae tendineae are approximately 80% collagen, while the remaining 20% is
made up of elastin and endothelial cells.
