The trabeculae carneae (columnae carneae) are rounded or irregular muscular columns which project from the whole of the inner surface of the ventricle, with the exception of the conus arteriosus.
They are of three kinds:
- some are attached along their entire length on one side and merely form prominent ridges,
- others are fixed at their extremities but free in the middle,
- while a third set (musculi papillares) are continuous by their bases with the wall of the ventricle, while their apices give origin to the chordæ tendineæ which pass to be attached to the segments of the tricuspid valve.
