Histology of Hoof Wall 

C indicates the coronary corium. The two arrow heads point to the dermal papilla (corium = dermis). Remember from lecture, the germinal coronary epithelium covering the tips of the papillae produce the tubular horn, whereas the germinal epithelium between the papillae produce intertubular horn. The tubular and intertubular horn produced by the coronary epithelium is the stratum medium. The long arrow indicates direction of growth.

Laminae are present at L. The laminar germinal epithelium produces the stratum internum. The coronary corium (C) is continuous with the laminar corium (LC).
