▪ bone
      expanded end of the long bones (bone) in animals, which ossifies separately from the bone shaft but becomes fixed to the shaft when full growth is attained. The epiphysis is made of spongy cancellous bone covered by a thin layer of compact bone. It is connected to the bone shaft by the epiphyseal cartilage, or growth plate, which aids in the growth of bone length and is eventually replaced by bone.
