Changes in the Appendicular Skeleton with Age01:09

Changes 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...
The Thoracic Cage: Ribs01:20

The Thoracic Cage: Ribs

Ribs are curved, flattened bones forming the thoracic cavity wall with the thoracic muscles. There are 12 pairs of thoracic ribs. The posterior ends of all the ribs articulate with the T1–T12 thoracic vertebrae. In contrast,the anterior ends of most ribs attach to the sternum via their costal cartilages.
Parts of a Typical Rib
A typical rib has a head, neck, and body. The posterior end of the rib is called the head, followed by a narrow neck. The head articulates primarily with the costal facet...
The Ratio of X Chromosome to Autosomes02:45

The Ratio of X Chromosome to Autosomes

In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.  
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female Drosophila...

Summary

This study introduces a new method for estimating age at death using the sternal extremity of the fourth rib. The formula Age = 10.43 (AB)(0.53) offers a reliable alternative for forensic anthropology.

Area of Science:

  • Forensic Anthropology
  • Osteology
  • Human Identification

Background:

  • The sternal extremity of the fourth rib is a recognized indicator for age estimation at death.
  • The Iscan "phase method" is currently a widely used technique for this purpose.

Purpose of the Study:

  • To develop and validate an alternative method for age estimation at death.
  • To utilize morphologic characteristics of the sternal extremity of the fourth rib.

Main Methods:

  • Morphologic characteristics of the articular surface (A), anterior/posterior walls (B), and superior/inferior edges (C) of the sternal extremity of the fourth rib were analyzed.
  • A numerical score was assigned to each parameter.
  • Regression formulae were developed, with "Age = 10.43 (AB)(0.53)" showing the best correlation.

Main Results:

  • The formula "Age = 10.43 (AB)(0.53)" demonstrated the strongest correlation between observed morphologic characteristics and chronological age.
  • The study sample comprised sternal extremities from 49 white males of known age, obtained during autopsies.

Conclusions:

  • The developed regression formula provides a viable alternative method for age estimation at death.
  • This method offers a new tool for forensic anthropologists and archaeologists in determining age from skeletal remains.
