Type of break is cervical and lumbar curvatures.
If there are no ossification centers, there are no osteoblasts, no osteocytes, no spongy bone, which in turn means no compact bone thus no flat bones which serves as a protection layer.
Osteoclasts are large bone cells with up to 50 nuclei. They remove bone structure by releasing lysosomal enzymes and acids that dissolve the bony matrix. Intramembranous ossification directly converts the mesenchymal tissue to bone and forms the flat bones of the skull, clavicle, and most of the cranial bones. While bone resorption is performed by large immune cells called osteoclasts, osteoblasts, a type of specialized connective tissue-related cells, is responsible for making new bone.
