When does growth stop in the development of long bones?

Question

Quizplus · Accepted Answer

Growth in long bones continues until the epiphysis, which is the rounded end of the bone, fuses with the rest of the bone. This occurs during adolescence and is typically completed by the time a person reaches their early twenties. Choice A is incorrect because the emergence of molars has no effect on long bone growth. Choice B is incorrect because the proximal femoral epiphysis is only one of many epiphyses in the body and growth does not stop at this point. Choice C is incorrect because the fusion of the diaphysis and epiphysis marks the end of longitudinal growth but not necessarily the end of growth altogether. Choice D is also incorrect because the shift of the physis to the front of the bone, known as the "apical shift," is a normal part of growth but does not mark the end of growth.
