Animal Chiropractic Module 4 – Extremities Practice Exam

Which structure suspends the coffin bone within the hoof like velcro?

Frog Laminae Sole Coronary band

Correct Answer:

Laminae

Explanation:

Laminae suspend the coffin bone inside the hoof. The interlocking sensitive laminae (in the dermis) and insensitive laminae (in the hoof wall) form a velcro-like connection that anchors P3 to the hoof wall while still allowing a little give to distribute weight. If these laminae are damaged, as in laminitis, the suspension weakens and the coffin bone can sink or rotate. The frog mainly aids shock absorption and blood circulation, not bone suspension; the sole protects the bottom and bears weight; the coronary band is where hoof growth occurs, not the tether holding the bone in place.
