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.
A line marks the Earth's equator. A line marks the Earth's equator. The equator is defined as an imaginary line drawn on the Earth and spaced equally between the North and South Pole. An example of the equator is the latitude of 0Â°.he imaginary great circle around the earth's surface, equidistant from the poles and perpendicular to the earth's axis of rotation. It divides the earth into the Northern Hemisphere and the Southern Hemisphere. b. A similar great circle drawn on the surface of a celestial body at right angles to the axis of rotation.
