The origin of the hoof is as a form of protection to the distal phalanx and stems from local modifications of the epidermis, [[Skin - Anatomy & Physiology#Dermis|dermis]] and subcutaneous layers. There is great variation in the shape and types of hooves across different species and this is often due to the multi-role nature of the hoof. In some species the hoof may play an important role in non-locomotion roles such as digging or being used as a weapon. The hoof also acts as a shock-absorber in that the hoof acts to reduce the concussion of foot impact on the structures of the distal limb. It has also been suggested in some species that the elastic nature of components of the hoof may aid the return of blood to the [heart].
