The moderator band (also known as septomarginal trabecula) is a muscular band of heart tissue found in the right ventricle of the heart. It is well-marked in sheep and some other animals, and frequently extends from the base of the anterior papillary muscle to the ventricular septum.Click to see full answer. Subsequently, one may also ask, what is the moderator band in the heart and its function?Its main function is to convey the right branch of the atrioventricular bundle of the conducting system. The septomarginal trabecula forms the anteroinferior border between the superior, smooth outflow tract of the ventricle and the trabeculated inflow tract.Furthermore, what is the function of the Trabeculae Carneae in the heart? The trabeculae carneae also serve a function similar to that of papillary muscles in that their contraction pulls on the chordae tendineae, preventing inversion of the mitral (bicuspid) and tricuspid valves towards the atrial chambers, which would lead to subsequent leakage of the blood into the atria. Similarly, you may ask, what is a moderator band in left ventricle? Location: Also called false tendons, false chordate and left ventricular moderator bands among other names, left ventricular bands are fibromuscular structures in the left ventricle crossing the cavity or simply joining nearby trabeculations or papillary muscles left ventricle.What is the difference between Trabeculae Carneae and Pectinate muscles?Pectinate muscles make up the part of the wall in front of this, the right atrial appendage. Pectinate muscles of the atria are different from the trabeculae carneae which are found on the inner walls of both ventricles. The pectinate muscles originate from the crista terminalis.
