What is the growth plate?

The growth plate is a layer of cartilage at the end of bones that allows the bones to get bigger.

A growth plate is developing cartilage near the wider portion of long bones. The cartilage is in place to allow for growth of the individual. Once a person has reached maturity, usually around 18 to 25, the cartilage ossifies into solid bone.
