The medial end of the clavicle is the last epiphysis to fuse in the human body. At what age does this epiphyseal fusion typically complete?
- A 16-18 years
- B 18-20 years
- C 21-25 years ✓
- D 25-30 years
Correct answer: C. 21-25 years
Explanation
The medial clavicular epiphysis is the last to fuse in the human body, typically completing union between 21 and 25 years of age. This is a critical forensic landmark for determining whether an individual has attained 21 years. The acromial end fuses earlier, around 18-20 years. No other epiphysis fuses as late as the sternal end of the clavicle.
