Quizplus · Accepted Answer

Bone age refers to the average chronological age at which centers of ossification form and fusion of growth plates takes place. It is determined by examining X-rays of the bones in the hand and wrist and comparing them to established charts that plot the age at which specific bones normally appear and fuse. This information is useful in determining the timing and rate of growth and development, as well as identifying abnormalities and delays in bone maturation. Option A is incorrect because secondary centers of ossification are not used to determine bone age in humans; only primary centers are considered. Option C is incorrect because the technique used to determine fossil age is radiometric dating, not X-raying bones. Option D is not correct because option B is accurate.
