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 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.
Common digital extensor: part originates from the humerus and travels distally, to become the common digital extensor tendon at the bottom third of the radius (see above). The other part originates from the lateral tuberosity of the radius, and inserts into the tendon. This muscle extends the carpal, pastern, and coffin joints.
The house mouse is best identified by the sharp notch in its upper front teeth. House mice have an adult body length (nose to base of tail) of 7.5–10 centimetres (3–4 in) and a tail length of 5–10 cm (2–4 in). The weight is typically 11–30 g (3 ⁄ 8 –1 oz).
The limbs of the horse are structures made of dozens of bones, joints, muscles, tendons, and ligaments that support the weight of the equine body. They include two apparatuses: the suspensory apparatus, which carries much of the weight, prevents overextension of the joint and absorbs shock, and the stay apparatus , which locks major joints in ...

The domestic horse is almost alone among extant equines in having chestnuts on the hind legs. [5] Chestnuts are absent from the hind legs of asses and zebras. [6] The majority of domestic horses have chestnuts on all four legs, as does the Przewalski's horse, [6] but a few horse breeds are reported to lack chestnuts on the hind legs. [6] These ...
Because the hock takes a great deal of strain in all performance disciplines, correct conformation is essential if the horse is to have a sound and productive working life. Common conformational defects include sickle hocks, post-legged conformation/straight hocks, cow hocks, and bowed hocks. Depending on the use of the horse, some defects may ...
