Wrist bones.
The joint between the horse's hock and hip is called the Stifle joint.
this long bone that runs from the hock to the fetlock is called the cannon bone
A horses leg is called a leg, but it has several names for different areas of the leg like cannon, hock and gaskin.
Horses do not have knees in the same sense that humans do. They have front legs with knees that are equivalent to our wrists, and hind legs with hocks, which are the equivalent to our ankles. Instead of bending their legs at the "knee," horses extend their legs or "lock" them in place.
Chestnut applies to horses in two ways; one is the color, which is reddish brown. Another is the bony protrusion from above the horses knee in the front, and from the inner hock on the back. This is in no way harmful to horses, it is present on all horses.
Most humans treat horses well, but some humans (unfortunately) abuse them.
The left medial hock refers to the inner side of the left hind leg joint in quadruped animals like horses and cows. It is an important joint for mobility and stability in the animal's hind limbs. Issues with the left medial hock can affect the animal's ability to move properly.
For a young horses' joints to fully fuse, it takes 3-5 years. This is why horse racing is very dangerous because the horses are not fully developed. Do not jump/race/work hard with immature horses!
It depends on wich part you are talking about. there are three. The feltlock, the pastern, and the ergot.
An animal's hock is the joint in the hind leg that is comparable to the human ankle. It is located between the knee and the fetlock joint. In horses, for example, the hock is crucial for mobility and bears a significant amount of weight during movement.
The horse is built for speed, and its muscles are bunched at the top of its legs. The horse's knee is called the stifle and is only slightly below the 'body' level. The hock, less than halfway down the leg, corresponds to the human ankle. From the hock to the fetlock, the bones that correspond to those in the human foot are fused. The fetlock is the first toe joint - the horse stands on the tip of a single toe.
Because there is no muscle below the knee/hock to cushion the bones
