The vertebral column usually contains 54 bones: 7 cervical vertebrae, including the atlas (C1) and axis (C2) which support and help move the skull, 18 (or rarely, 19) thoracic, [2] 5-6 lumbar, 5 sacral (which fuse together to form the sacrum), and 15-25 caudal [2] vertebrae with an average of 18. Differences in number may occur, particularly in ...
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 ...
Antagonist to brachiocephalicus. Supports the back, helps to pull the body of the horse forward when a limb is extended and placed on the ground, also helps to flex the scapulohumeral joint. Longissimus capitis: originates on the first 2 thoracic vertebrae and the cervical vertebrae. Inserts into the atlas.
Color of the tail is linked to the overall equine coat color of the horse and is generally not a breed trait unless the overall color is selected for within a breed. However, in coat colors where point coloration occurs, the tail is one part of the anatomy that will exhibit the contrast color, along with the mane, lower legs, and tips of the ears.
Most horses have 18 thoracic vertebrae. The processes at the withers can be more than 30 centimetres (12 in) long. Since they do not move relative to the ground as the horse's head does, the withers are used as the measuring point for the height of a horse. Horses are sometimes measured in hands – one hand is 4 inches (10.2 cm). Horse heights ...

The height of horses is measured at the highest point of the withers, where the neck meets the back. [23] This point is used because it is a stable point of the anatomy, unlike the head or neck, which move up and down in relation to the body of the horse.
