EPIPHYSEAL DISC – 2
The following pages will deal with the lighter-colored band seen in cross sections of long bones between the epiphysis and the diaphysis. Its is called the epiphyseal line (n sections), epiphyseal disc, growth cartilage, or strong>metaphysis.
It is in the epiphyseal disc the the events that result in the longitudinal growth of a bone take place. In the next pages details of its structure and of the growth mechanism of the diaphysis of long bones will be presented.
It is important to bear in mind that the growth cartilage or metaphysis or the epiphyseal line, seen in histological sections as a band, is actually a thin disc formed mostly of hyaline cartilage.
