A child who has had abnormal development of the membranous bones has a broad skull with associated facial and dental anomalies. Which other bones are most likely to also be affected?
In a syndrome called cleidocranial dysostosis, absence of pa of the clavicles accompanies a broad skull, and facial and dental anomalies. Note that you could also have answered this question by noting that of the bones listed, only the clavicles form by intramembranous ossification. The femurs , metatarsals , phalanges , and tibias are cailaginous (formed by endochondral ossification) rather than membranous bones. Ref: Mescher A.L. (2013). Chapter 8. Bone. In A.L.
