Pressure (Continued)

I am now a bone cell in the front cannon of the 2 year old German horse, Overdose. I am located about mid-thickness in the illustration below.
What happens to me as Overdose motors down the track?

The many illustrations in this post hopefully will support the conclusions which are totally my own speculation. Bone cells as many materials hook or attach together in a matrix symbolized by the illustration below.
We see this sort of patterning in electron microscopic images of silicon, below:
Here are images of proteins in matrix. Notice the 5nm resolution that I'm presuming is rather small.
and, below, illustration of spider webb cells. Notice the hooks that hold them together.
and, finally, bone imaging. The below is "low resolution". Very unfortunately I was unable to copy the high resolution imaging of the same photo that appears in Journal of Bone. The high resolution of the below shows crisp perfect patterning of the matrix much as you see in the other images above.
and below, osteoperotic bone showing a similar pattern. One may imagine "pressure" working on this bone as opposed to the solid bone cells above.
