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 following tendons are the main tendons found in the lower leg. When they pass over a joint, they are protected in a tendon sheath, which contains synovial fluid as a lubricant. Common digital extensor: the common digital extensor muscle becomes tendon in the bottom third of the radius and continues down the front of the leg. The tendon ...
The suspensory apparatus consists of the suspensory ligament, the check ligament, the deep digital flexor tendon, the superficial flexor tendon, the common digital extensor tendon and the sesamoid bones. [11] Horses use a group of ligaments, tendons and muscles known as the stay apparatus to "lock" major joints in the limbs, allowing them to ...
In horses and oxen, the distal part of the tendon of insertion of quadriceps ("below" the patella) is divided into three parts. An elaborate twisting movement of the patella allows the stifle to "lock" in extension when the medial portion of the tendon is "hooked" over the bulbous medial trochlear ridge of the distal femur.
A draft horse sleeping while standing up. The stay apparatus is an arrangement of muscles, tendons, and ligaments that work together so that an animal can remain standing with virtually no muscular effort. [1] It is best known as the mechanism by which horses can enter a light sleep while still standing up. [2]
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).
Poor footing: working a horse on uneven or slippery footing can cause tendon strain, as well as deep, “thick” footing. Each of these factors encourage the overextension of the fetlock and knee during work. Several of these factors at once can add up. Direct trauma to a tendon: such as when a horse hits its front leg with a hind hoof.
Curb is defined in older literature as enlargement secondary to inflammation and thickening of the long plantar ligament in horses. [1] However, with the widespread use of diagnostic ultrasonography in equine medicine, curb has been redefined as a collection of soft tissue injuries of the distal plantar hock region.
