Geometric morphometric study of sexual dimorphism in malaysian mandibles

Sexual Dimorphism Using Geometric Morphometric Approach

A geometric morphometric study into the sexual dimorphism of the human scapula.

Sex determination is vital when attempting to establish identity from skeletal remains. Two approaches to sex determination exists: morphological and metrical. The aim of this paper was to use geometric morphometrics to study the shape of the scapula and its sexual dimorphism. The sample comprised 45 adult black male and 45 adult black female scapulae of known sex. The scapulae were photographe...

Nonmetrical sexual dimorphism in mandibles of Brazilian individuals

The sexual differences can be determined through morphological characteristics found in the ramus and body of mandible. The accuracy in determining sex is variable and the degree of sexual dimorphism in mandibles is different for each population. The aim of this study was to analyse nonmetric morphological characteristics of mandibles in adult Brazilian individuals, determining the anatomical v...

Sexual dimorphism of the suprascapular notch – morphometric study

INTRODUCTION The concept of the study was to compare the morphometry of the suprascapular notch (SSN) in females and males because its size and shape may be a factor in suprascapular nerve entrapment. MATERIAL AND METHODS The measurements of 81 scapulae included morphological length and width, maximal width and length projection of the scapular spine, and width and length of the glenoid cavit...

Sexual dimorphism in the mandible of indigenous South Africans: A geometric morphometric approach

Introduction Much of our understanding of modern human skeletal variation in southern Africa is derived from anthropological techniques based on the traditional linear metrical system. With specific reference to either the whole skull or its functional components, there is a long history of such research (e.g. refs 1–8). Recent research has also focused on using various skeletal elements to qua...
