"Some will curvature of the spine usually doesn't stand up straight."
the center of curvature is the ORIGIN of the radius of curvature
The cervical curvature is the most superior spinal curvature.
no not all the time
No, the cervical curvature is considered the secondary curvature, the primary curvatures are the thoracic and sacral curvatures. The lumbar curvature is also considered the Secondary Secondary curvature (yes that's two secondarys, as in the second secondary)
Secondary
The respelling of "curverature" is "curvature".
Radius of curvature divided by tube diameter. To get the radius of curvature, imaging the bend in the tube is a segment of a circle, the radius of curvature is the radius of that circle.
Curvature is a general term to describe a graph. Like, concave or convex. Radius of curvature is more exact. If the curve in a 'small' section is allow to continue with the same curvature it would form a circle. that PRETEND circle would have an exact radius. That is the radius of curvature.
1/aAccording to Wikipedia,"The canonical example of extrinsic curvature is that of a circle, which has curvature equal to the inverse of its radius everywhere. Smaller circles bend more sharply, and hence have higher curvature. The curvature of a smooth curve is defined as the curvature of its osculating circle at each point."
The stomach has a greater and lesser curvature. The greater curvature is the more lateral of the two.
Cervical curvature
the centre of sphere is known as centre of curvature
