- Ossification is the development of
bone from cartilage. It occurs
throughout childhood until adulthood.
- Bones have a tough outer
layer called the 'Periosteum'.
- As development continues
there are 3 centres of
ossification:- in the 'Diaphysis'
(middle) and 'Epiphyses' (end).
- Diaphysis is the middle
of the bone (shaft).
- Epiphyses is at the end of the bone (end section).
- Epihysis is on the top of
the bone (growth plate).
- Epihysis is on the top of
