When epiphyses fuse to the diaphyses:

Question

Quizplus · Accepted Answer

Fusion of the epiphyses to the diaphyses is the process of completing bone growth, which typically occurs during adolescence. Once this process is complete, the bone has attained its full adult length, and further growth is no longer possible. Therefore, choice B ("full adult height is attained") is the correct answer. Choice A is incorrect, as long bone growth is actually complete once the epiphyses fuse to the diaphyses. Choice C is also incorrect, as the adolescent growth spurt occurs prior to the fusion of the epiphyses. Finally, choice D is incorrect, as this process is largely determined by genetics and hormones, rather than environmental factors.
