The main idea is understanding which structure acts as the primary stabilizer and load-bearing ligament of the leg. The suspensory ligament is a thick, strong band that runs along the back of the cannon bone and attaches to the proximal sesamoid bones near the fetlock. Its job is to support the fetlock during weight bearing and propulsion, absorbing shock and preventing the joint from collapsing under load. Because of this heavy, high-load role, it is larger and more robust than other ligaments in the region. The other options don’t provide the same stabilizing, weight-bearing support: the check ligament is a smaller band that limits tendon movement, while the lateral extensor tendon and the flexor tendon are tendons (muscle-to-bone connections), not ligaments. So the largest ligament in the leg is the suspensory ligament.
