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 bones and joints of the equine forelimb distal to the wrist (or carpus): The fetlock (metacarpophalangeal joint) is located between the cannon bone (third metacarpal) and the long pastern bone (proximal phalanx).
Frontal bone: creates the forehead of the horse; Parietal bones: extend from the forehead to the back of the skull; Occipital bone: forms the joint between the skull and the first vertebrae of the neck (the atlas) Temporal bones: contain the eternal acoustic meatus, which transmits sound from the ear to the cochlea (eardrum)
Flexes the carpus and lower joints, Deep digital flexor: has three heads. One originates from the humerus, one on the proximal side of the radius, one on the proximal side of the ulna. Their tendons travel distally and join at the carpus, to become the deep digital flexor tendon (see above). Extends the elbow, flexes the carpus and lower joints.
On this horse, the ergot is a small point at the back of each fetlock Ergot on a heavy horse with feathers. The ergot is a small callosity (Calcar metacarpeum and Calcar metatarseum) on the underside of the fetlock of a horse or other equine. Some equines have them on all four fetlocks; others have few or no detectable ergots.

A coffin bone coffin bone shown in relationship to a horseshoe. The coffin bone, also known as the pedal bone (U.S.), is the distal phalanx, the bottommost bone in the front and rear legs of horses, cattle, pigs and other ruminants. It is encased by the hoof capsule. In horses and other odd-toed ungulates it is the third phalanx, or "P3"; in ...
