What corium produces the white line?

The white line is the seam where the outer hoof wall (epidermis) meets the sole, created by the attachments of the sensitive laminae to the hoof wall. Those attachments come from the terminal papillae of the sensitive laminae, a part of the corium. The epidermal laminae grow over these papillae to form the hoof wall, and where this junction is exposed at the edge of the sole, the white line appears. The other corium areas—around the coronary band, under the sole, or under the frog—support other structures and do not form this boundary.
