Figure 1.

Anatomical sagittal plane section of an equine thoracic hoof. Proximal is to the right in images 2–7. (a) Dermal and epidermal tissues of the hoof and the distal phalanx parietal region. In the detailed images, note the coronary band to extensor process distance (1, A), the tubular hoof wall (2–3, P1 and P2), and the lamellar layer and the sublamellar dermis (2–3, D1 and D2) at the proximal (2) and distal (3) levels, respectively. Note the distal phalanx apex to hoof wall distance (4, B) and the sole dermis (5, S). (b) In the enlarged detail, note the lamellar layer (6–7, L1 and L2) and the sublamellar dermis (6–7, C1 and C2) at the proximal (6) and distal levels (7), respectively.
