An automated tool for measuring human limb bones
… automatically takes multiple measurements on bones using 2D images. Results show that this method takes significantly less time and performs as accurately as standard measurement methods in the field of anthropology. This technology has implications for streamlining data collection practices …

Multivariate asymmetry and allometry in human limb bones as a basis for osteometric sorting
The size and shape of a limb bone relative to another bone holds a great amount of information needed to individualize a commingled assemblage. This study maximizes discriminating information found in long bone measurements with multivariate analyses of allometry and asymmetry. Previous research on …

Giraffa camelopardalis: limb bone histology through ontogeny
… the microanatomy and histology of giraffe limb bones through ontogeny. Mid-diaphyseal sections of humeri, radii, metacarpals, femora, and tibiae of 14 individuals representing individuals of known sex, as well as at different ontogenetic stages (foetal, juveniles, subadults, and adults). …

A Comparison of Limb Development of the Salamanders Plethodon Cinereus and Ambystoma Mexicanum
Tetrapod limbs exhibit a wide variety of developmental variation. Amphibians alone display a fair amount this variation. Here, the development of both limb pairs in the species Plethodon cinereus and Ambystoma mexicanum are compared. Using histology and microCT on embryonic and juvenile specimens, …

Comparison of the long bone microstructure of two southern African marine birds, the Cape gannet (Morus capensis) and the African penguin (Spheniscus demersus) with respect to their aquatic adaptations
… efficient flying bird, uses both fore- and hind limbs to propel itself under water. On the other hand, the flightless penguin swims underwater using only its forelimbs. In this study, the long bones of ten penguins and nine gannets were compared in terms of microanatomy and histology with respect …

Morfologia do esqueleto apendicular e das cinturas peitoral e pélvica dos Titanosauridae (Dinosauria: Sauropoda) do neocratáceo de Minas Gerais, Brasil
Seventy-two appendicular and girdle bones referred to the family Titanosauridae (Dinosauria: Sauropoda) are described and figured. They have been found in Continental Upper Cretaceous strata of Brazil (Bauru Basin), near the city of Peirópolis, state of Minas Gerais. All of them were collected, …

Mechanism of Hip Dysplasia and Identification of the Least Energy Path for its Treatment by using the Principle of Stationary Potential Energy
… energy of four rigid-body components of lower limb bones. Five muscles are identified and modeled because of their effect on DDH reduction. Clinical observations indicate that reduction with the Pavlik Harness occurs passively in deep sleep under the combined effects of gravity and the …

Alutiiq Engineering: The Mechanics and Design of Skeletal Technologies in Alaska's Kodiak Archipelago
… compact tissue of reindeer antler, cervid long bones, and the limb bones of the California sea lion. Cervid compact limb tissue is stiff, strong, and brittle, while reindeer antler is flexible and highly fracture-resistant (tough). Air-drying hardens all skeletal tissues, and greatly increases …

The Skeletal Biology of Hibernating Woodchucks (<i>Marmota monax</i>)
… and estimated stresses acting on woodchuck bones were investigated in conjunction with computed tomography scans and three-point bending tests to determine bone density, geometry, and mechanical properties of the long bones throughout the year. In addition, serum protein expression was …

The Nuances of Locomotor Strategies in Suspensory Primates (Apes): Locomotor Costs in Terms of Skeletal Injury
… severity, and remodeling are examined in limb bones from skeletons of 141 wild-caught primates according to four major predictions. First, the suspensory genera will show a greater percentage of limb bone fractures than quadrupedal baboons. Second, among suspensory apes, the brachiating …

Targeted Deletion of Functionally Validated Enhancers Defines Their Role In Mouse Limb Development
… development of specific structures, such as the limb. Manipulation of enhancers at their endogenous loci, such as the deletion of such elements, leads to a better understanding of the regulatory interactions, rules and complexities that contribute to faithful and variant gene transcription – the …

Development and Validation of a Child Finite Element Model for Use in Pedestrian Accident Simulations
… accidents including fractures of lower limb bones and ruptures of knee ligaments were predicted by the model. The child model was accepted to be used according to Euro-NCAP protocol, so it will be used by safety researchers in the design of front ends of new vehicles in order to increase …

Adaptation at High Altitudes: A Comparative Analysis of Body Size and Proportions in Ancient Tibetan and Lowland Chinese Populations
… By incorporating broader archaeological limb bone data and contemporary anthropometric datasets from China into Bayesian hierarchical models, it further examines how climate, altitude, and socio-cultural factors have shaped morphological variation across space and time. Part I: …
