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.
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).
This muscle turns and extends the neck, and makes up the topline if well developed. The Trapezius is a flat, sheet-like muscle that begins at the Occipital bone and ends at the spines of the 7th cervical and all the thoracic vertebrae. It lifts the shoulder and forehand, and if this muscle is well developed, the horse will work in a good outline.
The limbs of the horse are structures made of dozens of bones, joints, muscles, tendons, and ligaments that support the weight of the equine body. They include two apparatuses: the suspensory apparatus, which carries much of the weight, prevents overextension of the joint and absorbs shock, and the stay apparatus , which locks major joints in ...
An arched neck is desirable in a horse for any sport. Ewe-neck, with muscling on the underside. A ewe neck or upside-down neck bends upward instead of down in the normal arch. This fault is common and seen in any breed, especially in long-necked horses but mainly in the Arabian Horse and Thoroughbred. The fault may be caused by a horse who ...
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]
The omohyoid muscle is a muscle in the neck. It is one of the infrahyoid muscles. It consists of two bellies separated by an intermediate tendon. Its inferior belly is attached to the scapula; its superior belly is attached to the hyoid bone. Its intermediate tendon is anchored to the clavicle and first rib by a fascial sling.
