Trabecular part of right ventricle
Pars trabecularis ventriculi dextri
- Synonym: Apical trabecular component of right ventricle
Definition
The trabecular part of the right ventricle refers to the central and apical region of the right ventricular cavity that is characterized by a complex meshwork of muscular ridges and projections known as trabeculae, and contains the papillary muscles. This region is anatomically distinct from the smooth-walled inlet (which contains the tricuspid valve and chordae tendineae) and the outflow tract (infundibulum or conus), which is also smooth-walled.
