Summary
This study reveals that the number of lamellae in human trabecular bone decreases with age, offering insights into anatomical aging and potential palaeodemographic applications.
Area of Science:
- Biological Anthropology
- Human Anatomy
- Gerontology
Background:
- Anatomical aging studies serve dual purposes: understanding human senescence and estimating age at death.
- Trabecular bone remodelling patterns are key indicators of normal aging processes in humans.
Purpose of the Study:
- To investigate normal aging patterns in human trabecular bone remodelling.
- To explore the relationship between age and the structure of trabecular bone in the ilium.
Main Methods:
- Analysis of iliac bone samples from 25 males without diseases affecting bone structure.
- Microscopic examination (100x magnification) of 1 cm2 bone prisms to count double lamellae in osteons.
- Statistical analysis using linear regression to correlate lamellar counts with age.
Main Results:
- A high, negative linear correlation (r=-0.83, p<0.001) was found between age and the mean number of lamellae per osteon.
- The log of mean lamellar counts regressed linearly with age, showing no heteroscedasticity.
- New trabecular bone formation was observed in disk-shaped osteons with distinct double lamellar structures.
Conclusions:
- The number of lamellae in trabecular bone decreases significantly with age.
- While the current sample size is limited for direct age estimation, the method shows potential for palaeodemographic applications.
- This study highlights the utility of microscopic bone analysis in understanding human aging.

01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
01:29Bone Formation by Intramembranous Ossification
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...

01:27Compact Bone
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

01:09Spongy Bone
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

01:09Changes in the Appendicular Skeleton with Age
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
