Like the right ventricle, the left also has trabeculae carneae, but there is no moderator band.
2.
From its attachments it was thought to prevent overdistension of the ventricle, and was named the " moderator band ".
3.
These purkinje fibers ( p-fibers ) found in the hearts moderator bands are a specialized cardiac muscle fiber that causes the heart to contract.
4.
The moderator band is important because it carries part of the right bundle branch of the AV bundle of the conduction system of the heart to the anterior papillary muscle.
5.
In addition to these muscular ridges, a band of cardiac muscle, also covered by endocardium, known as the moderator band reinforces the thin walls of the right ventricle and plays a crucial role in cardiac conduction.
