How long does is usually take for ossification to be completed in humans?

The process of ossification, or the formation of bone tissue, begins in the fetus and continues until early adulthood. The age at which ossification is completed varies among individuals and depends on factors such as genetics, nutrition, and overall health. In general, ossification is considered complete when all the growth plates in the body have fused, which typically occurs between the ages of 18 and 25 years. However, some bones, such as the clavicle (collarbone), may complete ossification as early as 18 years, while others, such as the vertebrae, may not be fully ossified until around 25 years of age. It's worth noting that the timing of ossification can be affected by certain medical conditions, such as growth disorders or hormonal imbalances.
