Hoof growth occurs by cell division in which area?

Growth happens in the epidermal tissue at the coronary band, where cells constantly divide to form new horn. These cells in the outer horn-producing cell layer divide and differentiate into horn-forming cells, keratinize, and then move outward to become the hoof wall and related horn. The underlying dermal layer (the corium) provides blood supply and sensation but does not itself generate horn tissue. So the site where the horn grows by cell division is the outer horn-producing cell layer of the sensitive structures.
