Abstract/Description
-
Research on the human rib has shown that the sternal end of this bone manifests differences in age, sex and race. It was also found that intercostal variation may affect the expression of these traits. The purpose of this study is to osteometrically analyze intercostal variation and sexual dimorphism in ribs 1-7 from a known sample of American black males (N = 110) and females (N = 52) collected from recent forensic autopsy cases. Results indicate that although intercostal variation is...

It was also found that intercostal variation may affect the expression of these traits. The purpose of this study is to osteometrically analyze intercostal variation and sexual dimorphism in ribs 1-7 from a known sample of American black males (N = 110) and females (N = 52) collected from recent forensic autopsy cases. Results indicate that although intercostal variation is significant, there is too much overlap to metrically determine rib position. Sexual dimorphism is sufficient to develop discriminant function formulae that separate males and females with a minimum accuracy of 75% (rib 1) and a maximum of 83% (rib 4). However, these functions are population and rib specific. This research confirms earlier findings on ribs 3-5, and expands the potential to determine sex from ribs 1-7.

Abstract/Description

Previous hypotheses have suggested that maxillary sinus volume (MSV) is dependent on nasal cavity volume (NCV), and while NCV is highly correlated with climate, MSV is a passive by-product. To test these hypotheses 39 dried adult human crania from different climatic regions were examined using CT technology. MSV and NCV were regressed against each other and cranial size-variables using least squares and reduced major axis analysis. Analysis of variance (ANOVA) tests were also utilized to...

To test these hypotheses 39 dried adult human crania from different climatic regions were examined using CT technology. MSV and NCV were regressed against each other and cranial size-variables using least squares and reduced major axis analysis. Analysis of variance (ANOVA) tests were also utilized to identify significant differences in MSV and NCV between populations. Results suggest that MSV and NCV are not significantly correlated, and while NCV scales with isometry relative to skull size, scaling properties of MSV were not significant. ANOVA results show that although there are significant differences in MSV between populations, they are not due to climatic influences.
