Описание

There are two main papillary muscles in the right ventricle, anterior and posterior:

  • The anterior papillary muscle is the larger, and its chordæ tendineæ are connected with the anterior and posterior cusps of the valve:
  • The posterior papillary muscle sometimes consists of two or three parts; its chordæ tendineæ are connected with the posterior and medial cusps.

In addition to these, some chordæ tendineæ spring directly from the ventricular septum (Septal papillary muscle), or from small papillary eminences on it, and pass to the anterior and medial cusps.
