mmer Session II 2018)> Discussions> Chapte 7 discussion This is a graded discussion: 100 points possible due Chapte 7 discussion Jay Beckenstein went to weight-lifting camp in the summer between seventh grade and eighth grade. He noticed that the camp trainer put tremendous pressure on him and his friends to improve their strength. After an especially vigorous workout, Jay's arm felt extremely sore and weak around the elbow. He went to the camp doctor, who took X- rays and told him that his injury was serious, for the "end of his upper arm bone was starting to twist off." What had happened? Could the same thing happen to Jay's 23-year- old sister, Trixie, who was also starting a program of weight lifting? Why or why not?

Most likely the epiphyseal plate - bone junction has separated. This would not happen to jay's 23 years old sister trixie because at her age, epiphyseal plates have been replaced by bone and are no longer pressent.
1)Jay's epiphyseal plates of his long bones are still growing, due to his age.
2)The heavy weights caused permanent damage to his epiphyseal plates, stunting the grouth of the bone.
3)Jay's sister should have epiphyseal plates that are already calcified, so she should not have the same problem.
4)Jay's bone has not completely calcified yet, and it is still cartilage making it weaker than calcified bone.
