What is another word for papillary muscle?
Pronunciation: [pˈapɪləɹi mˈʌsə͡l] (IPA) 
The papillary muscles are small muscles located in the heart, specifically in the ventricles. These muscles serve an important function in preventing the backflow of blood in the heart valves. Although there are no direct synonyms for papillary muscle, there are other terms used to describe the muscles located in this area of the heart, such as trabeculae carneae, chordae tendineae, and valve-supporting muscles. Trabeculae carneae refers to the ridges and folds that line the walls inside the ventricles, while chordae tendineae are thin tendons that connect the papillary muscles to the heart valves. Valve-supporting muscles, as the name suggests, provide support to the heart valves during their opening and closing.
