Uberon definition : the supporting bundles of muscular fibers lining the walls of the ventricles of the
heart;
Uberon synonym : ventricle trabecula carnea;
Uberon related term : heart trabecula; ventricular trabecula; trabeculae carneae; trabecula of heart; cardiac trabecula;
Uberon Function note : The purpose of the trabeculae carneae is most likely to prevent suction that would
occur with a flat surfaced membrane and thus impair the heart's ability to pump efficiently.
The trabeculae carneae also serve a similar function to papillary muscles in that
their contraction pulls on the chordae tendineae, preventing inversion of the mitral
(bicuspid) and tricuspid valves, that is, their bulging towards the atrial chambers,
which would lead to subsequent leakage of the blood into the atria. So by the action
of papillary muscles on the atrioventricular valves, backflow of the blood from the
ventricles into the atria is prevented;
