Abstract
In addition to the papillary muscles of right ventricle referred to in anatomical
nomenclature, namely the anterior, posterior and septal, we have distinguished
the “conal papillary muscle” and the “papillary muscle of the posterior angle of
the right ventricle”. The conal papillary muscle was described by Luschka in the
17th century as the most constant of the septal papillary muscles. We have distinguished
the muscles of the posterior angle of the right ventricle as muscles
which would not be clearly classified as either septal or posterior muscles. Moreover,
the muscles of the posterior angle of the right ventricle are probably associated
with the transfer of the papillary muscles from the septum to the posterior
wall of the right ventricle during phylogenetic evolution. Some researchers
have classified them with the septal papillary muscles [11, 12], while others have
assigned them to the posterior group [5]. The morphology of the muscles was
classified using earlier categories for the posterior papillary muscles only. We
have adopted the concept of multi-apical and multi-segmental muscles [5].
