MICROANATOMY

Detailed explanation-1: -The epiphyses, which are wider sections at each end of a long bone, are filled with spongy bone and red marrow. The epiphyseal plate, a layer of hyaline cartilage, is replaced by osseous tissue as the organ grows in length. The medullary cavity has a delicate membranous lining called the endosteum.

Detailed explanation-2: -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-3: -Long bones have two ends called epiphysis and a shaft, or the middle portion of the bone, called the diaphysis.

Detailed explanation-4: -The epiphysis is at each end of a long bone. It contains mostly spongy bone. The metaphysis is the part of a long bone between the diaphysis and the growth plate. The growth plate (epiphyseal plate) is a thin disc of cartilage between the epiphysis and metaphysis.
