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.

Heterogeneous studies in terms of gender, age, data source, group of comparison, cycling level or modality practiced among others factors showed minor but important differences in results. Despite some controversial results, it has been observed that adult road cyclists participating in regular training have low bone mineral density in key regions (for example, lumbar spine). Conversely, other types of cycling (such as mountain biking), or combination with other sports could reduce this unsafe effect. These results cannot yet be explained by differences in dietary patterns or endocrine factors.
We need to see an ecosystem that goes with the rat to answer this question.
