Here's a breakdown of the hoof's structure:
* Outer layer: The hoof wall, made of tough keratin, acts as a strong, protective outer shell.
* Inner layer: The sensitive laminae, delicate layers of tissue that attach the hoof wall to the inside of the foot, provide a vital connection and blood supply.
* Sole: The sole is the bottom part of the hoof, also made of keratin. It cushions the foot and helps distribute weight.
* Frog: The frog is a triangular, rubbery structure at the back of the hoof. It aids in blood circulation and provides support for the hoof.
The hoof is essentially a natural shoe for the horse, protecting the sensitive structures inside the foot from injury and wear and tear.
