Can the trabeculae within the vertebral bodies be damaged without damaging the surrounding cortical bone?
Yes - if a large compressive load causes a stellate fracture in the end plate resulting in a Schmorl's node.

Are stellate fractures and Schmorl's nodes more common in the elder or in younger adults? Why?
Younger. The nucleus pulposa of the disk is still hydrated so there is fluid material present to be forced into the vertebral body.

What characteristics of the range of motion of an individual provide an indication of pathelogical abnormalities?
Excessive or reduced range of motion as compared to normal, or especially assymetrical range of motion._ However, unusual ranges of motion could merely be reflective of normal variation.

What are the 4 steps for determinining the center of rotation of a vertebra which has moved from one position in an x-ray to another as shown in another x-ray when one of the x-rays has been laid over the top of the other?
1. Determine and mark the same two points on the vertebra on each of the two images of that vertebra._ (the two points should be as far apart from each other as possible)_ 2. Draw a line connecting the point on one image to the same point on the other image._ (do that for each of the two points selected on the vertebra)_ 3. Draw a perpendicular bisector through each of the two lines._ 4. The intersections of the two perpendicular bisectors is the center of rotation for that movement.

How and why does the length of the spine typically vary during the course of a 24 hour period?
The spine is longer after sleeping because water is imbibed into the IVDs making them thicker (There is reduced load from your body weight on IVDs while you are horizontal)._ The spine is shortest just before going to bed because water is pushed out during the day when your are upright, putting more load (body weight) on the IVDs, making them thinner.
