While the fetlock is sometimes colloquially referred to as an "ankle", even by horse experts, that terminology is misleading. The ankle joint in humans corresponds to the hock of horses. The fetlock is a metacarpo- or metatarsophalangeal joint which corresponds to the human upper knuckle, such as that on the ball of the foot. This usage likely ...
Points of a horse. Equine anatomy encompasses the gross and microscopic anatomy of horses, ponies and other equids, including donkeys, mules and zebras.While all anatomical features of equids are described in the same terms as for other animals by the International Committee on Veterinary Gross Anatomical Nomenclature in the book Nomina Anatomica Veterinaria, there are many horse-specific ...
Skeleton of the lower forelimb. Each forelimb of the horse runs from the scapula or shoulder blade to the third phalanx (coffin or pedal) bones. In between are the humerus (arm), radius (forearm), elbow joint, ulna (elbow), carpus (knee) bones and joint, large metacarpal (cannon), small metacarpal (splint), sesamoid, fetlock joint, first phalanx (long pastern), pastern joint, second phalanx ...
The main purpose of the suspensory is to support the fetlock joint, preventing it from overextending. Injury to this ligament is an important cause of lameness in performance horses. The suspensory is a modified muscle, the equine equivalent of the interosseous muscle, which contains both tendon fibers and residual muscle fibers. [1]
The pastern is a part of the leg of a horse between the fetlock and the top of the hoof.It incorporates the long pastern bone (proximal phalanx) and the short pastern bone (middle phalanx), which are held together by two sets of paired ligaments to form the pastern joint (proximal interphalangeal joint).
This muscle extends the carpal, pastern, and coffin joints. It also flexes the elbow. Lateral digital extensor: originates from the lateral tuberosity of the radius and from the ulna, becomes the lateral digital extensor at the proximal portion of the metacarpus. This muscle extends the carpal and fetlock joints.
Fetlock is the common name for the metacarpophalangeal and metatarsophalangeal joints of horses, is a rotatory joint that can exhibit the greatest range of motion of any equine joint. [3] The fetlock joint is formed between the large metacarpal or metatarsal bone ( in the hindlimb and forelimb) and the proximal sesamoid bones. [4] Relation with ...
fetlock The joint above the pastern. [8]: 183–4 Anatomically, the metacarpophalangeal (front) and metatarsophalangeal (rear) joints of the horse, formed by the junction of the third metacarpal (forelimb) or metatarsal (hindlimb) bones (also known as the cannon bones) and the proximal phalanx distad (the pastern bone). Anatomically equivalent ...
