Horses have four limbs, just like us humans have two arms and two legs. The front limbs of a horse are called the forelimbs and the back limbs are the hind limbs.
Each limb has different parts that help the horse to move around. The upper part of each limb is called the shoulder and hip, and the lower part is called the leg. The leg has three main parts: the upper leg, the lower leg, and the hoof at the bottom.
The upper leg is the part of the leg closest to the horse's body. It's like your thigh, except much bigger and stronger. The lower leg is like your calf muscle and is covered with tendons that help the horse to move quickly and jump high. Lastly, the hoof is like a horse's "toe" and it's made of a hard material called keratin. Horses use their hooves to run and support their entire body while standing, so they are very important.
Horses also have joints in their limbs to help them move in different directions. For example, the knee joint in a horse's forelimbs allows the horse to bend their legs and move their feet forward. The ankle joint in the hind limb helps the horse to jump over things and move their feet quickly.
Overall, horses have amazing limbs that allow them to do incredible things like run really fast, jump over fences, and carry riders on their backs. With the help of their limbs, horses can move freely and gracefully, just like the amazing creatures they are!
