periosteum

periosteum

Dense membrane over bones. The outer layer contains nerve fibres and many blood vessels, which supply cells in the bone. The bone-producing cells of the inner layer are most prominent in fetal life and early childhood, when bone formation is at its peak. In adulthood they are less active but vital to continuous bone remodeling. When bone is injured, they multiply profusely to produce new bone.


periosteum [‚per·ē′äs·tē·əm]
(anatomy)
The fibrous membrane enveloping bones, except at joints and the points of tendonous and ligamentous attachment.

For the analyses, we used the total cross-sectional area (including marrow cavity and cortical bone, in square millimeters), cortical area (square millimeters), cortical thickness (millimeters), cortical bone mineral content (milligrams per millimeter), cortical bone mineral density (BMD; milligrams per cubic centimeter), total BMD (milligrams per cubic centimeter), and periosteal circumference (millimeters).
