Diaphysis

The diaphysis (pl: diaphyses) is the main portion (shaft) of a long bone (a bone that is longer than it is wide). 

The diaphysis has a tubular composition with a hard outer section of hard cortical bone and central portion with cancellous bone and bone marrow cavity.

It is formed by primary ossification (endochondral ossification) before longitudinal growth continues with secondary ossification at the physis.
