MICROANATOMY

Detailed explanation-1: -epiphysis, expanded end of the long bones 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 .

Detailed explanation-2: -The ends of a long bone contain spongy bone and an epiphyseal line. The epiphyseal line is a remnant of an area that contained hyaline cartilage that grew during childhood to lengthen the bone. All of the bones in the arms and legs, except the patella, and bones of the wrist, and ankle, are long bones.

Detailed explanation-3: -The ends of epiphyses are covered with hyaline cartilage ("articular cartilage").
