The main tendon in the hoof is the deep digital flexor tendon, which connects to the bottom of the coffin bone. The impact zone on the bottom of the hoof includes the sole, which has an outer, insensitive layer and a sensitive inner layer, and the frog, which lies between the heels and assists in shock absorption and blood flow.
Deep digital flexor: 3 tendons of the deep digital flexor muscle travel distally and join at the carpus, where they pass through the carpal canal, and travel distally along the back of the leg, finally inserting into the palmar side of the third phalanx. Below the knee/hock, the tendon is superficial to the suspensory ligament, but deep to the ...
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 ...
Long toes force the horse to pivot (break over) further forward over the toe. The toe acts as a lever arm, and its increased length makes it harder for the heels to rotate off the ground. This increases strain on the deep digital flexor tendon and the ligaments of the navicular bone. [10] An abscess has ruptured out of the coronary band of this ...
Knowledge of equine forelimb anatomy is especially useful for understanding navicular syndrome. The navicular bone lies behind the coffin bone and under the small pastern bone. The deep digital flexor (DDF) tendon runs down the back of the cannon and soft tissue in that area and under the navicular bone before attaching to the back of the ...
A ruptured tendon usually refers to the complete separation of a tendon. Tendon separation results in a complete loss of the tendon fibers, a marked increase in tendon cross-sectional area, and loss of support in the limb. [56] A totally ruptured superficial digital flexor tendon (SDFT) will cause a visible drop in the angle of the fetlock. [57]
Sesamoid bones: Bones embedded within a tendon. The horse's proximal digital sesamoids are simply called the "sesamoid bones" by horsemen, his distal digital sesamoid is referred to as the navicular bone. Ligaments and tendons hold the skeletal system together. Ligaments hold bones to bones and tendons hold bones to muscles.
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]
