Inside the hoof capsule the whole internal foot is covered with dermis. This is a tendon-like tissue full of arteries, veins, capillaries and nerves. Depending on its location the dermis is called solar, perioplic, wall, coronary, frog, bulbar or bar dermis. These various types of dermis produce different types of horn. For example the frog dermis (sensitive frog) produces frog horn (live frog) and the solar dermis produces sole horn (live sole).
