Quizplus · Accepted Answer

The prominent muscular ridges that run along the inner surface of the auricle and across the adjacent atrial wall are the pectinate muscles. The chordae tendineae are fibrous cords that connect the papillary muscles to the cusps of the atrioventricular valves. The foramen ovale is a temporary opening in the interatrial septum of the fetal heart. The papillary muscles are located in the ventricles and are attached to the chordae tendineae. The trabeculae carneae are irregular muscular ridges on the inner surface of the ventricles.
