Besides mechanical and protective function, bone serves as a keeper for marrow cells and an organ for regulation of calcium ion homeostasis. During aging, significant amounts of the bone are lost due to the loss of this delicate balance toward increased bone resorption coupled with decreased formation, which leads to net bone loss of the aging people ...

Baillière's Clinical Rheumatology, 1993
Bone can be divided into two kinds of tissue, cortical and trabecular bone. The skeleton comprises approximately 80% cortical bone, mainly in peripheral bones, and 20% trabecular bone, mainly in the axial skeleton. Bone density increases with skeletal growth to a peak in late adolescence or early adulthood.

Gerodontology, 1998
AbstractChanges in bone structure as a function of age have been studied by simple inspection, x‐ray imaging, stereo‐photography, deep field optical microscopy, circularly polarised light microscopy, and scanning electron microscopy (SEM), including both topographic and compositional backscattered electron (BSE) imaging modes.

This chapter will provide a general overview of the aging process followed by the potential effect that aging may have in bone biology. Three important aspects will be considered: decreased number of osteoblasts, increasing adipogenesis and significant osteoblast/osteocytes apoptosis during the aging process in bone.

Current Pharmaceutical Biotechnology, 2017
The decline of tissue function in ageing is a consequence of many changes in the gene expression and other extrinsic factors. The molecular mechanisms underlying these changes are heavily investigated with focus on regulation of time-lapse gene expression.

The purpose of this article has been to summarize the existing body of literature on the changes in the function of muscle and bone that occur as a consequence of aging. Throughout this article, the importance of distinguishing between aging and disuse has been a recurring theme.

Clinical Orthopaedics and Related Research, 1982
A survey was done of aging changes in compact and trabecular bone. During the past decade, noninvasive methods have demonstrated similar results for compact bone in large samples. Aging decreases of 3%/decade begin at about age 40 in both sexes and continue, but in women, an additional loss occurs after menopause, bringing their total rate of decrease ...

Skeletal development in average healthy individuals is maximal at age 25 in women and at age 30 to 35 in men. However, there are significant racial differences, skeletal mass being greater in black than in white individuals. This difference appears best accounted for by increased muscle mass in blacks.

Bone and fat connection in aging bone
Current Opinion in Rheumatology, 2008The fat and bone connection plays an important role in the pathophysiology of age-related bone loss. This review will focus on the age-induced mechanisms regulating the predominant differentiation of mesenchymal stem cells into adipocytes. Additionally, bone marrow fat will be considered as a diagnostic and therapeutic approach to osteoporosis.There ...

Reviews in Clinical Gerontology, 1998
In Europe, vertebral fracture incidence has increased 300–400% for women and more than 400% for men during the last 30 years. These data are age-adjusted and therefore highlight that there is a decrease in bone mass or bone quality from generation to generation.
