Anatomical terminology

The moderator band (also known as septomarginal trabecula) is a band of cardiac muscle found in the right ventricle of the heart. It is well-marked in sheep and some other animals, including humans. It extends from the base of the anterior papillary muscle of the tricuspid valve to the ventricular septum.
