The horse hoof (or hooves if you’re using the British spelling) is an exciting structure that plays a major role in supporting the horse while running, jumping, and playing all around
Even though horse hooves are made of bone, they aren’t just solid bones like you would find in your leg or your arm! They have a lot more going on inside them than you might expect at first glance.
Most people know that horses are one of the many animals that have hooves, but what most people don’t know about horse hooves is that they aren’t just solid bones, and the material that makes up the soft tissue of their hooves is different from the way that other animals, such as cows and sheep, have theirs made.
Find out what makes horse hooves so unique!
What Are Horse Hooves Made Of ?
Horse hooves are made up of the same types of tissue that make up your fingernails and hair. They’re actually extensions of your horse’s leg bones and are therefore mostly solid bone.
The outer material on the outside of the hoof is called the periople, and it’s similar to your fingernails as well! The periople works like an exoskeleton, providing support and protection to the hoof wall underneath.
This helps to prevent cracks or splits in your horse’s hooves as they run around and play with their herd mates.
It turns out, horse hooves consist of a combination of different types of tissue. The outer layer is covered with keratin, which is the same type of protein found in human nails and hair.
Beneath this layer, the corium is made up of a substance called cartilage. Cartilage helps provide support and flexibility for the hoof as it grows.
However, since cartilage can’t grow forever as bones do, every six months or so horses will shed their old hoof and replace it with a new one. Horse hooves come in all shapes and sizes depending on their breed, but on average the size of each part is about 1-3 inches long from heel to toe.
Horse Hoof Anatomy
The hoof is the hard and tough part at the end of a horse’s limb. It is an essential part of a horse’s anatomy, serving as protection for the delicate structures within.
The outer layer consists of horn-like plates called lamellae, while the inside contains sensitive tissue including blood vessels, nerves, and glands.
Together, these components help horses maintain balance and navigate uneven terrain without injury. In addition to being strong and durable, horse hooves are also extremely elastic which allows them to bend like shock absorbers.
When your horses walk on surfaces such as pavement or concrete, their elastic hooves help absorb the impact!
How Does the Hoof Grow?
A horseshoe is a protective device nailed onto the hoof of a horse, donkey, or pony which acts as a shield to protect it from wear and tear.
The shoe is affixed by being driven into the ground with a hammer, clinch nail, or screwdriver. However, the soft tissue of the hoof is living tissue; therefore nails should not penetrate too far so that they do not puncture it.
If this does happen then horses will walk on their fetlocks rather than their toes to avoid injury. In most cases, however, this only happens if someone tries to force-fit a horseshoe onto a horse’s hoof rather than allowing them time for their foot to grow accustomed to wearing one.
It takes about four weeks for the new layer of tissue to harden before shoes can be applied again. Horses don’t need shoes unless they’re working in an area where there is a lot of sharp gravel or other rough surfaces that could damage their hooves such as farms, stables, and riding arenas.
It is important to use good quality shoes fitted correctly because improperly fitted horseshoes can cause lameness in horses due to excessive stress put on their feet.
The Outer Sheath
Horse hooves start as thin skin on the front and back of the fetlock, or ankle. This skin grows thicker and tougher as it moves up the leg until it becomes a hard outer shell.
This outer sheath is made up of specialized tissue called cornified epidermal cells, which produce keratin – a tough protein found in human hair and nails.
They also create glycosaminoglycans, which give the outer sheath its rigidity. The inner side of the outer sheath has blood vessels and nerves so that when your horse needs protection, he can shift his weight and change his gait to make himself less vulnerable.
As long as your horse’s hoof maintains its shape, he can walk on rough terrain without hurting himself.
The Inner Cartilage Layer
As it turns out, horses’ hooves have a tough inner layer of cartilage. The top layer is called the periople and the bottom is called the frog.
Together these two layers create a very durable and protective armor for their feet. When these parts of the foot need to grow in size, they actually grow outside of the hoof capsule.
There’s an area on the coronet (the rounded edge) where skin cells form new horn-like structures. These form as many as five new nails each year. When this happens, the old nails wear down and fall off – which leaves room for more growth! It can take up to four months for these new nails to fully harden so don’t worry if your horseshoe starts falling off earlier than expected!
Why Should Horse Owners Care About Hoof Anatomy?
Horse owners should care about their horses’ hooves because, without them, their horses would have a hard time walking.
Horse-hoof anatomy is fascinating. The first part of the hoof is called the coronet and it contains blood vessels and nerves that supply the entire foot.
The middle part of the hoof called the frog provides cushioning when the horse puts its weight on it and makes sure water doesn’t seep into its sensitive structures.
Finally, the outer part of the hoof is called the wall. It protects all other parts of the foot from being damaged by objects in its environment like rocks or pieces of glass. Horses can also run faster with healthy feet because the wall helps to absorb shock while running.
If something happens to your horse’s hoof, make sure that you take him to your veterinarian as soon as possible so he can examine it.
The number one cause for problems with a horse’s feet is improper shoeing. When shoes become loose, an imbalance occurs between the front and hind limbs which can lead to lameness issues for your horse.
Additional Information on Hoof Anatomy from Equine Podiatry Network
The hoof consists of the coffin or pedal bone, the distal phalanx, and the proximal phalanx. The coffin or pedal bone is the largest part of the foot, and it can be seen at the bottom of a barefoot horse’s foot.
The distal phalanx is located on top of the coffin bone. It has two branches: one branch attaches to each side (or coronet) of the coffin bone.
The other branch attaches to the front surface of the distal phalanx. The proximal phalanx sits directly below and behind the distal phalanx. It extends into an area called the ground surface, which is also known as the bearing surface.
In conclusion, it turns out that horse hooves aren’t just made up of one part but two. The first part is the hard outer shell, or hoof wall, which is a form of keratin. This is what you see when you look at the outside of a horse’s feet. The second part is the softer inner core, or frog, which cushions and absorbs shock for the rest of the leg.
