Comet Smacked Neptune 200 Years Ago, Data Suggests. by Denise Chow, SPACE.com Staff Writer | July 23, 2010 02:48pm ET. New measurements performed by the European Space Agency's Herschel infrared space telescope indicate that a comet may have hit Neptune, the outer-most planet in our solar system, two centuries ago.
The growth plate, also known as the epiphyseal plate or physis, is the area of growing tissue near the ends of the long bones in children and adolescents. Each long bone has at least two growth plates: one at each end.The growth plate determines the future length and shape of the mature bone.he epiphysis is completely separated from the end of the bone or the metaphysis, through the deep layer of the growth plate. The growth plate remains attached to the epiphysis. The doctor has to put the fracture back into place if it is significantly displaced.
That's because there are a lot of nerves and blood vessels in that area that can be hurt along with the growth plate. Sometimes, a growth plate fracture can also cause the bone to grow more, but this has the same result: One limb ends up longer than the other. A less common problem is when a ridge develops along the fracture line.
