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.
The world is divided into four hemispheres based on lines of latitude and longitude. The equator is an imaginary line that is equidistant from the North and South Poles. This line falls at zero degrees latitude. The part of the Earth that is north of the equator is known as the Northern Hemisphere. The part of the Earth that is south of the equator is known as the Southern Hemisphere. The Western and Eastern Hemisphere are divided by zero degrees longitude which is known as the Prime Meridian.
