What is the function of the laminar corium?

• A. Transfer body weight to the hoof wall
• B. Produce keratin for the hoof
• C. Absorb shock at the coronet
• D. Store minerals

Answer: (A)

The laminar corium is the sensitive tissue that forms the interlocking laminae connecting the coffin bone to the hoof wall. Its main job is to transfer the body's weight from the skeleton down into the hoof wall by creating and nourishing these laminae, giving a strong, load-bearing connection. It also provides blood supply and sensation to the hoof tissues. Keratin for the hoof is produced by the epidermal tissue of the hoof, not by the laminar corium; shock absorption comes mainly from structures like the digital cushion and frog, and minerals are not stored by this tissue. So the strongest, most direct function of the laminar corium is transferring body weight to the hoof wall.
