What structure suspends the coffin bone within the hoof, functioning like Velcro?

• A. Sole
• B. Laminae
• C. Frog
• D. Coronary Band

Answer: (B)

Laminae form the interlocking attachment between the coffin bone (distal phalanx) and the hoof wall, suspending the bone inside the hoof. The tissue on the bone side (dermal laminae) interlocks with the tissue on the hoof wall side (epidermal laminae) in thousands of tiny folds, gripping the bone like Velcro and distributing the animal’s weight while keeping P3 properly aligned. This suspension system is essential for hoof function and is the part that laminitis targets when the bond weakens or fails. The sole provides surface protection and some support but does not suspend the bone; the frog helps with shock absorption and circulation but does not suspend the coffin bone; the coronary band is where new hoof wall grows, not the suspension mechanism.
