What is secondary ossification center?

Secondary ossification centers are areas of bone growth that form after the primary ossification center has already been established. They typically appear in the epiphyses (ends) of long bones and are responsible for the growth in length of the bone during puberty.

Secondary ossification centers develop later than primary ossification centers, usually around the time of puberty when hormonal changes trigger the growth spurt. They allow for continued bone growth and maturation as the individual reaches adulthood.

These secondary ossification centers also play a role in the eventual formation of mature bone structures such as the epiphyseal plate, where bone growth occurs until the individual reaches skeletal maturity.

Overall, secondary ossification centers are essential for proper bone growth, development, and the eventual formation of a mature skeletal system.
