Continuing With Bone Cells

Class is again called to order, and we'll have to sit through some pretty technical stuff to determine what happens to bone cells during the breeze, why the heck we get all that cannon bone heat for 12-24 hours post breeze, and how soon we can safely proceed to the next workout with our horse.

First I'll put out some NEW pertinent info concerning the single cannon bone cell extracted from mid bone. Hansma's website states the collagen is coated with mineral, whereas I just read from a Bone Journal that in fact on birth the collagen immediately begins mineralizing from the inside out and fairly quickly thereafter becomes completely calcified.

For understanding the exact process, nature, and end product of bone mineralization is extremely crucial for this reason: it is easy to visualize that pressure created by the forces during the breeze squeezing or compressing collagen and bone glue proteins, BUT how does compression affect a solid, rigid inorganic mineralized lattice illustrated above left?????? The puzzler becomes what happens to this lattice.

At 200nm (very small) Hansma's electron microscopy gives us this image of a bone cell:


You can visualize the above being squeezed together. But, what it really looks like is shown in another much larger Hansma image below:

This image shows mineralized bone to be very dense and solid, to the point that we have to wonder as the horse travels whether anything significant is happening at all. To answer this we have to really deconstruct and break down the process, and I'll get to this next post.
