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-an imaginary line around the Earth forming the great circle that is equidistant from the north and south poles; the equator is the boundary between the northern and southern hemispheres. great circle-a circular line on the surface of a sphere formed by intersecting it with a plane passing through the center.. 1. (Physical Geography) the great circle of the earth with a latitude of 0Â°, lying equidistant from the poles; dividing the N and S hemispheres. 2. (Mathematics) a circle dividing a sphere or other surface into two equal symmetrical parts. 3. (General Physics) See magnetic equator.
