It forms the "forearm" of the horse along with the ulna. Ulna: caudal to the radius, it is fused to that bone in an adult horse. Shoulder joint (scapulohumeral joint): usually has an angle of 120-130 degrees when the horse is standing, which can extended to 145 degrees, and flexed to 80 degrees (such as when the horse is jumping an obstacle).
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 ...
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 ...
Pulls the forelimb forward, raises scapula in collection. Cervicalis ascendens: originates at the transverse process of the final 3-4 cervical vertebrae, inserts into the first rib. Cutaneous coli: originates from the cariniform cartilage and inserts into the cervical fascia.
The coracoid process acts as an attachment and origin for a large number of muscles (attached muscles not labeled here). The coracoid process is a thick curved process attached by a broad base to the upper part of the neck of the scapula; [2] it runs at first upward and medially; then, becoming smaller, it changes its direction, and projects forward and laterally.
While this slightly closes the angle between the clavicle and the scapula, it also widens the shoulder. [4]: 40 The scapula can be elevated and depressed from the neutral position to a total range of 10 to 12 centimetres (3.9 to 4.7 in); at its most elevated position the scapula is always tilted so that the glenoid cavity is facing superiorly.
The laid back scapula slides back to the horizontal as the horse lifts its front legs, increasing the horse's scope over fences. [1] A sloping shoulder has better shock-absorption and provides a comfortable ride because it sets the withers back, so a rider is not over the front legs.
In the horse, the biceps' function is to extend the shoulder and flex the elbow. It is composed of two short-fibred heads separated longitudinally by a thick internal tendon which stretches from the origin on the supraglenoid tubercle to the insertion on the medial radial tuberosity.
