Bones of the lower limb, present in both the front and hind legs, include the cannon bone (3rd metacarpal/3rd metatarsal), splint bones (2nd and 4th metacarpal/metatarsal), proximal sesamoid bones, long pastern (proximal or 1st phalanx), short pastern (middle or 2nd phalanx), coffin bone (distal or 3rd phalanx), and navicular bone (distal ...
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 ...
The splint bones, (metacarpal or metatarsal II and IV), which are remnants of two of the five toes of prehistoric horses, run down either side of the cannon bone.They narrow as they go from the carpal or tarsal joint down, and form a "button" at the bottom or their length, a few inches above the fetlock.
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 ...
Fetlock joint: the joint between the cannon bone and the pastern. Fetlock is the common name in horses, large animals, and sometimes dogs for the metacarpophalangeal and metatarsophalangeal joints (MCPJ and MTPJ). Although it somewhat resembles the human ankle in appearance, the joint is homologous to the ball of the foot.
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).
In equines, is a very large bone and provides the major support of the body weight of the horse. The term cannon may also encompass the soft tissues as well as the second and fourth metacarpal or metatarsal bones, called splint bones which may form ossified bridges of bone, called splints which often form after trauma to the area. canner (US) 1.
Flexor carpi radialis: originates from the humerus and inserts into the proximal side of the second metacarpal. Flexes the elbow, extends the carpus. Ulnaris lateralis: originates on the lateral side of the humerus, inserts into the accessory carpal bone and on the proximal side of the lateral splint bone. Flexes the carpus, extends the elbow.
