Ossification of the ends of long bones _____. A secondary ossification center will appear in each epiphysis (expanded end) of these bones at a later time, usually after birth. Ossification occurs toward both ends of the bone from the primary ossification center, and it eventually forms the shaft of the bone in the case of long bones. * Want to see this answer and more?
