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 ...
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 ...
Extends the hip joint, adducts the limb. Semitendinosus: originates from transverse processes of 1st and 2nd coccygeal vertebrae and ventral side of tuber ischium. Inserts into the cranial side of the tibia and the tuber calcis. Flexes the femoropatellar joint, causes inward rotation of the leg, and extends the tarsus and hip.
Skeleton of a horse. The skeletal system of the horse has three major functions in the body. It protects vital organs, provides framework, and supports soft parts of the body. Horses typically have 205 bones. The pelvic limb typically contains 19 bones, while the thoracic limb contains 20 bones.
At the stifle joint, a "hook" structure on the inside bottom end of the femur cups the patella and the medial patella ligament, prevents the leg from bending. [5] Cattle have a stay apparatus which allows them to rest individual limbs, [3] but cattle generally do not sleep standing up. [6] The ancient Dinohippus had a rudimentary stay apparatus
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 even-toed ungulates such as cattle, it is the third and fourth (P3 ...
The limb is forcibly flexed for between 30 seconds and 3 minutes, [25] depending on the joint and practitioner preference, and the horse is immediately trotted off. An increase in lameness following a flexion test suggests that those joints or surrounding soft tissue structures may be a source of pain for the horse.
The present-day conformation of the hoof is a result of a progressive evolutionary loss of digits I, II, IV and V of the basal pentadactyl limb, with changes in bones, joints, and the hoof capsule. The resulting conformation allows a heavy, strong body to move with high speed on any ground, and most efficiently on open, hard, flat areas like ...
