It’s not that simple. Bone formation is a dynamic process and changes based on external influence. Bone mass renews itself every 90 days during the younger years. The external influence causes bone to change and thicken as required. It’s why heavier people have bigger bones and why orthodontics work by putting pressure on the teeth to move them. The pressure causes the bone to reform around the tooth to equalize and stabilize the pressure.
The same thing happens with skull binding. The plates move, elongate, change shape and thicken based on the pressure. The location of the spinal cord opening moves also to compensate for the change in the center of gravity of the new mass configuration.
In other words, all of the changes seen are the body’s natural response to the external forces and ability to adapt. This is further modified by the effects of brain pressure on regulating hormone areas.
