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.
Equator: 0Â° 0' 0. The Equator is an imaginary circle drawn around a planet (or other astronomical object) at a distance halfway between the poles. By definition, the equator is latitude 0Â° 0' 0 and is one of the five major circles of latitude that mark maps of the Earth. An equinox in astronomy is the event when the Sun can be observed to be directly above the Earth's equator.
