multiple cholce question
the small clumps of muscle to which the chordae tendineae are attached are called the ______ muscles.
coronary
cuspid
auricular
papillary

Explanation:

• Coronary: Refers to blood vessels related to the heart, not muscle - clump attached to chordae tendineae.
• Cuspid: Relates to teeth or heart valves (bicuspid, tricuspid), not the muscle in question.
• Auricular: Pertains to the ear - like auricles of the heart (atrial appendages), not relevant here.
• Papillary: Papillary muscles are small muscle clumps in the ventricles attached to chordae tendineae, which prevent valve prolapse during ventricular contraction.

Answer:

papillary
