Question

The mitral valve is supported by

• A. Bundle of His
• B. Ductus Arteriosus
• C. Foramen ovale
• D. Chordae tendineae

Answer 1

The correct option is D Chordae tendineae

The valve between the left atrium and the left ventricle of the heart, which has two tapered cusps, called as the mitral valve. The inelastic chordae tendineae are attached at one end to the papillary muscles and the other to the valve cusps. Papillary muscles are fingerlike projections from the wall of the left ventricle. Chordae tendineae from each muscle are attached to both leaflets of the mitral valve. These valve leaflets are prevented from prolapsing into the left atrium by the action of tendons attached to the posterior surface of the valve, chordae tendineae.

So, the correct answer is option D.
