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.
Archaic humans hunted wild horses for hundreds of thousands of years following their first arrival in Eurasia. Examples of sites demonstrating horse butchery by archaic humans include: the Boxgrove site in southern England dating to around 500,000 years ago, where horse bones with cut marks (with a horse scapula possibly exhibiting a spear wound [3]) are associated with Acheulean stone tools ...
The horse has a wide field of monocular vision, as well as good visual acuity. Horses have two-color, or dichromatic vision, which is somewhat like red-green color blindness in humans. [30] Because the horse's vision is closely tied to behavior, the horse's visual abilities are often taken into account when handling and training the animal.
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 ...
It is forbidden by Jewish law, because the horse is not a ruminant, nor does it have cloven hooves. Similarly to dogs, eating horses was a taboo for the Castro culture in Northwestern Portugal, and it is still a counter-cultural practice in the region. [81] Horse meat is forbidden by some sects of Christianity.
The lower leg bones of a horse correspond to the bones of the human hand or foot, and the fetlock (incorrectly called the "ankle") is actually the proximal sesamoid bones between the cannon bones (a single equivalent to the human metacarpal or metatarsal bones) and the proximal phalanges, located where one finds the "knuckles" of a human.
Digitigrade and unguligrade animals have relatively long carpals and tarsals, and the bones which correspond to the human ankle are thus set much higher in the limb than in a human. In a digitigrade animal, this effectively lengthens the foot, so much so that what are often thought of as a digitigrade animal's "hands" and "feet" correspond to ...
