What Is the Pars Interarticularis?

The metric relationship joint line is also translated as "metric relationship staggered line". The line connecting the joint points from quantitative change to qualitative change. Originally a term in astronomy. In astronomy, the point at which the elliptical orbits of the celestial bodies of the solar system cross the ecliptic is called the zodiac intersection, and the straight line connecting the intersection points attracted by the center of the sun is called the intersection line. Hegel, Germany, first proposed the term philosophically. He believes that "the process of this change of mass unity [scale], that is, the process of changing from mere quantitative change first, then quantitative change to qualitative change, we can use the intersecting line as a metaphor to help understand" ( Little Logic "). ^[1]
