It mediates many of its biological actions via IGF-1, which acts on the epiphyseal plates of long bones also known as the growth plates. All females demonstrated complete fusion by 16 years with no significant differences between ancestral groups. During childhood, the growth plate matures, its total width decreases and eventually it disappears at the end of puberty with complete replacement by bone along with cessation of longitudinal growth. This mini review summarizes hypotheses and theories postulated in the literature regarding growth plate maturation and epiphyseal fusion.

The key role of estrogens for skeletal growth is demonstrated by the findings that both males and females with estrogen deficiency, caused by a mutation in the aromatase gene, display no clear pubertal growth spurt and continue to grow into adulthood owing to a lack of epiphyseal fusion in the long bones, which results in increased adult height. The epiphyseal plate is the growth zone between the diaphysis (shaft) of the long bone and the epiphysis (end) of the long bone. The results also show that the attainment of reproductive maturity in red deer occurs slightly before skeletal maturity. Epub 2007 Jul 20. Have You Registered For Bloody Words 2014 Yet?

The answer lies in long bone growth. A long bone begins in the fetus as a hyaline cartilage model, then the time of birth a secondary center of ossification or epiphysis develops at each end of the developing long bone. How do tiny infant bones mature to an adult size that could be as much as five or six times bigger? the end of a long bone, initially separated from the shaft (diaphysis) by a section of cartilage that eventually ossifies so that the two portions fuse together Also called: epiphysis cerebri (ˈsɛrɪˌbraɪ) the technical name for pineal gland Derived forms of epiphysis epiphyseal or epiphysial (ˌɛpɪˈfɪzɪəl), adjective Between puberty and adulthood the bone development overtakes completely and destroys the cartilage. 2008 Jan;68(1):4-15. doi: 10.1111/j.1365-2265.2007.02960.x.
