摘要：In recent decades (late twentieth century), have been reported multiple anatomical variations in relation to the concepts described classic, so what once was described as an anatomical variant in some cases has become predominant, not quite often proposing a revision of international anatomical terminology. This article is specifically addressed on the morphology of the papillary muscles of the two ventricles, describing the differences between the left and the right anterior ventricular walls.
