The suspensory and sesamoidian ligaments are important to what function of the limb?

These ligaments are key players in the stay apparatus, a passive system that lets the limb bear weight with little muscular effort. The suspensory ligament runs down the back of the cannon bone toward the fetlock, and the distal sesamoidean ligaments connect the sesamoid bones to the proximal phalanx. When the limb bears weight, these structures tauten and resist abnormal movement at the fetlock, helping to support the joint and keep the limb in a stable position. This arrangement allows standing and weight-bearing with much less muscle fatigue. It isn’t the primary mechanism for pure flexion or for absorbing shocks; its main role is passive support to enable standing and weight-bearing.
