spninal cord staight- mean loss normal curvature spine which affect movement spine
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.
What does spinal cord mean?
a curving or bending
The radius of curvature and the focal length mean the same so the radius of curvature is also 15 cm.
I think you mean spondylolisthesis or spondylosis. The first is where one vertebrae comes out of alignment of the rest and the second is a curvature of the spine. Surgery would be either a spinal fusion, or insertion of Harrington rods and hardware.
An exaggerated curvature of the thoracic (upper back). The curvature is outward which gives the appearance of a hump or rounded upper back.
If you are having an L5 S1 foraminotomy surgery it means the surgeons will enlarge the passageway of the first spinal nerve in your 5th lumbar vertebra.
They're probably refering to lateral curvature, which would be scoliosis.
Well, scoliosis is a curvature of the spine. The cervicothoracic part deals with the location of the curve. The cervical region is the neck, and the thoracic is the upper back. So the cervicothoracic scoliosis would be a curvature of the spine in the neck/upper back
There are two most important types of curvature: extrinsic curvature and intrinsic curvature. The extrinsic curvature of curves in two- and three-space was the first type of curvature to be studied historically, culminating in the Frenet formulas, which describe a space curve entirely in terms of its "curvature," torsion, and the initial starting point and direction. There is also a curvature of surfaces in three-space. The main curvatures that emerged from this scrutiny are the mean curvature, Gaussian curvature, and the shape operator. I advice to read the following article: http://mathworld.wolfram.com/Curvature.html Moreover, I advise add-on for Mathematica CAS, which do calculations in differential geometry. http://digi-area.com/Mathematica/atlas There is a tutorial about the invariants including curvature which calculates for curves and surfaces. http://digi-area.com/Mathematica/atlas/ref/Invariants.php
It's good news -- no spinal stenosis.
