Question

When does basiocciput fuses with basisphenoid?

• A. 18 to 22
• B. 22 to 25
• C. 14-16
• D. 12-14

Answer 1

The Correct Option is A

In forensic medicine, the fusion of bones can be a critical marker for determining age. In particular, the fusion of the basiocciput with the basisphenoid is a well-documented event. The basiocciput is the base portion of the occipital bone, and the basisphenoid is the base of the sphenoid bone. Their fusion is an important indicator for age estimation in young adults. The question asks when these bones fuse, and we have several options: 18 to 22, 22 to 25, 14-16, and 12-14. Based on anatomical studies, the correct answer is that the basiocciput fuses with the basisphenoid between the ages of 18 to 22 years. This process typically marks the end of adolescence and the transition to early adulthood. During this period, the final ossification processes occur, completing the bone maturation that started earlier during the teenage years.
