Section K: At the Clinic
1. A doctor has just viewed the x-rays of a 12 year old male and has found that where the growth plate should be is instead filled with what seems to be newly formed compact bone. The doctor has diagnosed the boy with premature ossification of the epiphyseal plate. What effects if any will the doctor now need to share with the parents related to their son's future growth?
2. A 75 year-old woman and her 9 year old-granddaughter were in a train crash in which both sustained trauma to the chest while seated next to each other. X ray showed that the grandmother had several fractured ribs, while her granddaughter had none. Explain these surprisingly different findings.
