Detailed explanation-3: -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.

Detailed explanation-4: -The diaphysis is the long, curved shaft that contains a central region called the medullary cavity (marrow cavity). It also contains compact bone that is very strong and dense and consists of units called osteons. The compact bone contains the yellow bone marrow that is responsible for storing adipose tissue.
