Papillary muscles & cordae tendineae of the heart

This photo is taken of a herbivore's heart, personally bisected by @nasarkhaan (Founder, Medicogram), demonstrating Papillary muscles and Cordae tendineae right in.The papillary muscles are the muscles located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves (also known as the mitral and tricuspid valves) via the chordae tendineae (The white cords in the given photo) and contract to prevent inversion or prolapse of these valves during systole or ventricular contraction.
