During hyperextension the accessory ligaments are lengthened while the proper ligaments are shortened.

The accessory ligament and the proximal margin of the volar plate are flexible and fold back upon themselves during flexion.

Pectineus: originates from the prepubic tendon, the accessory ligament, and the cranial side of the pubis.

The most important accessory ligaments of the sacroiliac joint are the sacrospinous and sacrotuberous ligaments which stabilize the hip bone on the sacrum and prevent the promonotory from tilting forward.

The most common injuries in the forelimb occur to the interosseous ligaments and the superficial digital flexor tendons, and less commonly the accessory ligament of the deep digital flexor tendon.

The longitudinal fibers are greatest in amount at the upper and front part of the capsule, where they are reinforced by distinct bands, or accessory ligaments, of which the most important is the iliofemoral ligament.

Each is strengthened at its posterior and medial part by an accessory ligament, which is attached below to the body of the axis near the base of the odontoid process, and above to the lateral mass of the atlas near the transverse ligament.
