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 ...
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).
The Hindquarters. Short Hindquarters. Measured from the point of hip to the point of buttock, the hindquarters should be ideally at least 30% of length of overall horse. Anything less is considered short. Most horses are between 29 and 33%; 33% is typically "Ideal," Thoroughbreds may have a length reaching 35%.
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 ...
If a horse is highly collected, the center of balance will be farther back, regardless of gait, than if the horse is in an extended frame. For movements such as a rein back or the levade, the center of balance of horse and rider may be further back than at a standstill, due to the shift of weight and balance to the hindquarters of the horse
Related to the concept of collection, impulsion helps a horse effectively use the power in its hindquarters. To achieve impulsion, a horse is not using speed, but muscular control; the horse exhibits a relaxed spinal column, which allows its hindquarters to come well under its body and "engage" so that they can be used in the most effective ...
Antagonist to brachiocephalicus. Supports the back, helps to pull the body of the horse forward when a limb is extended and placed on the ground, also helps to flex the scapulohumeral joint. Longissimus capitis: originates on the first 2 thoracic vertebrae and the cervical vertebrae. Inserts into the atlas.
A horse that is content will usually have the dock of the tail in a relaxed state, not moving other than to sway with the natural movement of the animal. In cold weather, horses may stand with their hindquarters facing into the wind and their tails clamped tightly to their buttocks in order to protect their bodies from the weather.
