Participates in healing of bone fractures Bones ossified in Membrane Parietal bone Temporal bone Upper occipital squamosa Frontal bone …see Yochum 2 forms of ossification **within cartilage** : PRIMARY OSSIFICATION SECONDARY OSSIFICATION PRIMARY OSSIFICATION: Cartilaginous tissue from mesenchymal cells transforms to bone * Lengthens bone SECONDARY OSSIFICATION:...
