Bone growth is a vital process that occurs throughout life, primarily during childhood and adolescence. It involves the formation of new bone tissue, which is essential for increasing bone size and strength. This process is regulated by various factors, including hormones like growth hormone and sex hormones, as well as nutrients such as calcium and vitamin D. There are two main types of bone growth: intramembranous ossification and endochondral ossification. Intramembranous ossification occurs in flat bones, like those in the skull, while endochondral ossification is responsible for the growth of long bones, such as the femur. Both processes ensure that bones develop properly and can support the body effectively.
