Trabeculae Carneae are the muscular ridge in the ventricles; which term describes these structures?

Explanation:
Trabeculae carneae are muscular ridges lining the inner walls of the ventricles. The term that describes these structures is exactly their name: trabeculae carneae. They differ from the structures in the atria called pectinate muscles, which are the analogous ridges there. The other options are arteries that carry blood, not ventricular muscle ridges: one goes to the lungs, another to the head and neck, and the third travels along the front surface between the ventricles. So, the muscular ridges inside the ventricles are called trabeculae carneae.
