Diaphysis

Assoc Prof Craig Hacking ◉ ◈ and Dr Jeremy Jones ◉ et al.

The diaphyses (singular: diaphysis), sometimes colloquially called the shafts, are the main portions of a long bone (a bone that is longer than it is wide) and provide most of their length.

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

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