Metaphysis
From Wikipedia, the free encyclopedia
The metaphysis is the body of cartilage that separates the epiphyses and the diaphysis of long bones during growth. It is this part of the bone that grows during childhood; as it grows, it ossifies near the diaphysis and the epiphyses. At roughly 18 to 25 years of age, the metaphysis stops growing altogether and completely ossifies into solid bone.
Epiphyseal plates are located in the metaphysis and are responsible for growth in the length of the bone.
