<P> The coffin bone , also known as the pedal bone ( U.S. ) , is the bottommost bone in the equine leg and is encased by the hoof capsule . Also known as the distal phalanx , third phalanx , or `` P3 '' . The coffin bone meets the short pastern bone or second phalanx at the coffin joint . The coffin bone is connected to the inner wall of the horse hoof by a structure called the laminar layer . The insensitive laminae coming in from the hoof wall connects to the sensitive laminae layer , containing the blood supply and nerves , which is attached to the coffin bone . The lamina is a critical structure for hoof health , therefore any injury to the hoof or its support system can in turn affect the coffin bone . </P>
