Does the skull get thicker with age?
Discussion. For both the males and females, the general trend of the full skull thickness was a slight increase with age. This trend was greatest in the frontal and parietal regions of the skull. Bone growth and remodeling is a product of both systemic and mechanical loading and regulation.
