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 ...
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.
Helps to raise the shoulder toward the head, and raise the neck upward. Scalenus: originates on the cranial and lateral side of the first rib, inserts into the transverse process of the cervical vertebrae (C4-C7). Semispinalis capitis: originates on the cervical vertebrae and first 6-7 thoracic vertebrae.
The shoulder girdle [5] or pectoral girdle, [6] composed of the clavicle and the scapula, connects the upper limb to the axial skeleton through the sternoclavicular joint (the only joint in the upper limb that directly articulates with the trunk), a ball and socket joint supported by the subclavius muscle which acts as a dynamic ligament. While ...
Digits may be specialized for different forms of locomotion. A classic example is the horse's development of a single toe (monodactyly). [3] Other hooves, like those of even-toed and odd-toed ungulates, and even the hoof-like foot of extinct hadrosaurs, [9] may be regarded as similar specializations.
In the horse, 84%, 15%, and 3% of the total triceps muscle weight correspond to the long, lateral, and medial heads, respectively. [11] Many mammals, such as dogs, cattle, and pigs, have a fourth head, the accessory head. It lies between the lateral and medial heads. [3]
