Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes
The Anatomical Record, EarlyView.Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

The 9+ month marathon: How pregnancy may have shaped human endurance capacities
The Anatomical Record, EarlyView.Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in

The mechanism of labor in nonhuman primates: A look inside
The Anatomical Record, EarlyView.Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...

Simultaneous anterior and posterior dislocation of hips: a case report and review of literature
Chinese Journal of Traumatology, 2012 【Abstract】The presence of anterior hip dislocation along with contralateral posterior hip dislocation in the ab-sence of other major traumas is a distinctly rare injury pattern. We report such a case, along with a review of previous cases.

Hip: Traumatic and Overuse Injuries.
The hip is a complex load-bearing joint susceptible to both acute traumatic and chronic overuse injuries. Traumatic injuries, such as acute fractures, dislocations, apophyseal avulsions, and muscle tears, typically follow high-energy events. In contrast,

Tribocorrosion of total hip replacements [PDF]
, 2012 The performance of metal-on-metal total hip replacements is largely determined by their propensity to degrade in vivo. Degradation occurs through the complex interactions between wear and corrosion (termed tribocorrosion) and leads to the production of ...

The Anatomical Record, EarlyView.Abstract The cortical bone structure of long bone diaphyses changes throughout growth via skeletal modeling and has important implications for bone strength and structural integrity. Ontogenetic trends in diaphyseal structure have been identified in both chimpanzees and humans but it is not yet clear how these trends compare given notable differences ...

A study of gender issues within hip hop dance in contemporary society [PDF]
, 2013 The principle aim of this dissertation is to examine how members of a British all-female hip hop dance group have become professional hip hop dancers despite the gender issues attached to hip hop dance and its originally underground nature.

Human evolution and the obstetrical dilemma: The pelvic floor hypothesis
The Anatomical Record, EarlyView.Abstract Human childbirth is mechanically difficult because a large‐headed, broad‐shouldered fetus must pass through a comparatively narrow, twisted bony birth canal. Traditional explanations of this “obstetrical dilemma” emphasize the role of bipedal locomotion in inhibiting the evolution of a wider, more spacious pelvis.
