1 It extends sagittally through the epiphysis, transversely through the epiphyseal plate and coronally through the distal tibial metaphysis. 2  Occurs in older children/young adolescents in 18 months just prior to epiphyseal plate closure (about 12-15 years).
An equator is the intersection of a sphere 's surface with the plane perpendicular to the sphere's axis of rotation and midway between the poles.he latitude of the Earth's Equator is by definition 0Â° (zero degrees). The Equator is one of the five notable circles of latitude on Earth, with the others being the two Polar Circles: the Arctic Circle and the Antarctic Circle, and the two Tropical Circles: the Tropic of Cancer and the Tropic of Capricorn.
In our lesson on hemispheres, we learned that a hemisphere is half of the earth. The equator is the imaginary line that runs all the way around the world, dividing it into two equal halves, the Northern Hemisphere, north of the equator, and the Southern Hemisphere, south of the equator.outhern Hemisphere: the half of the earth that is south of the equator. Prime Meridian: an imaginary line that goes all the way around the earth, dividing it into two equal halves, an eastern half and a western half.
