The diaphysis (/daɪˈæfᵻsᵻs/) is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat).
It is a middle tubular part composed of compact bone which surrounds a central marrow cavity which contains red or yellow marrow. In diaphysis, primary ossification occurs.
Ewing's sarcoma tends to occur at the diaphysis.

I met a girl and we ran away
I swore I'd make her happy every day
And how I made her cry
Two faces have i
Sometimes mister I feel sunny and wild
Lord I love to see my baby smile
Then dark clouds come rolling by
Two faces have i
One that laughs one that cries
One says hello one says goodbye
One does things I don't understand
Makes me feel like half a man
At night I get down on my knees and pray
Our love will make that other man go away
But hell never say goodbye
Two faces have i
Last night as I kissed you neath the willow tree
He swore he'd take your love away from me
He said our life was just a lie
And two faces have i
