This study investigated the path of emergence of the mental nerve in a number of human population groups. Skeletal material comprised 117 Negro skulls (53 males), 114 caucasoid skulls (62 males) and 100 pre-contact Maori skulls (70 males). In each case, the path of emergence was classified into posterior, anterior, right-angled or multiple. Those cases with(More)
Sex differences in the number of muscle fibers in the larynx of clawed frogs (Xenopus laevis) develop after metamorphosis. In order to examine possible contributions of neural innervation to this process, we prepared sections of the laryngeal nerve from tadpole stage 56, when the sexes can first be distinguished, through adulthood, and counted axons on(More)
Understanding the effects from long-term exposure to individual ambient air pollutants and mixtures of pollutants is necessary for adequate assessment of health risk. This study examined quantitative and temporal alterations in tracheobronchial mucociliary clearance function and bronchial epithelial secretory cells in rabbits exposed to sulfuric acid (125(More)
The bifid mandibular condyle has been described as a condition of unknown aetiology and uncertain pathogenesis. Many see it as the product of accidental trauma or forceps delivery, with the two heads occurring one behind the other in the sagittal plane. In bioanthropological literature, "bifid condyle" often describes pitting in the sagittal plane, dividing(More)
A sample of pre-European Polynesian and Melanesian mandibles, modern Asian Indians and cadaveric European mandibles were investigated to establish the prevalence of a subcondylar tubercle and to attempt to relate its presence to mandibular function. Among the three population samples, the subcondylar tubercle appeared 1.5 times more frequently among the(More)
OBJECTIVE The most recent study of the relationship between the maxillary artery and the lateral pterygoid muscle was published in this journal in 2008.(1) Given the controversy surrounding this relationship, our purpose was to present data gathered from New Zealand caucasoid cadavers over several years. STUDY DESIGN Both sides of 92 caucasoid adult(More)
Brown (2012: LB1 and LB6 Homo floresiensis are not modern human (Homo sapiens) cretins, Journal of Human Evolution) makes errors of fact, omission and interpretation. Brown's comments refer, among others, to (1) delayed growth and development indicated by unfused epiphyses, (2) postcranial limb proportions: limbs to trunk, between limbs, and within limbs,(More)
Rhinocerebral zygomycosis is a rare but dangerous fungal infection that affects primarily diabetic patients in ketoacidosis but other debilitated patients as well. A high index of suspicion among primary care physicians will lead to earlier diagnosis and help reduce the severe morbidity and mortality associated with the condition. Zygomycosis should be(More)

The chance discovery of a paper by Rottstock et al. (1983) comparing the individual diameters of 4,497 teeth from 711 skulls from anthropologically-different populations (Europeans, Negroids, Mongoloids, Melanesians) provided the impetus to add our measurements of 449 teeth from 89 Polynesians (mainland Maoris, Chatham Island, Wairau Bar) to the series. We(More)
We noted the similarity in mandibular profile between a 27,000-year-old skull from China and a 160-year-old Polynesian skull. Both had a more vertical ramus, a curved inferior border, and no chin. The European mandible has a greater gonial angle, an antegonial notch, and a chin. Is the presence of a chin sufficient to distinguish European mandible from(More)
