The U-shaped mandible is the strongest, largest, and only mobile bone of the skull housing the lower dentition. The anatomy of this sturdy bone allows it to perform its strategic functions such as elevation and
Germinal matrix hemorrhage (GMH) is a devastating neurodevelopmental condition affecting preterm infants, but why blood vessels in this brain region are vulnerable to rupture remains unknown. Here we show that microglia in prenatal mouse and human brain interact with nascent vasculature in an age-depen...
After the proper anesthetic depth was reached, the skull was exposed, and the surrounding skin and tissue were retracted. The skull was then cleaned of any connective tissue and scored to improve adhesion and mechanical stability. A bone screw (19010-00; FST), with a short piece of stainless...
"When we excavated it, the skull was actually looking out through that perforation. It was quite interesting, but whether it was done purposefully is difficult to know," O’Reilly told Live Science. Ancient burials The burial site is estimated to be 2,500 years old, and was found when res...
Bodies aren’t always required. If you need to draw a head with the help of anatomy tools, skull models are an immense help. A life-size flesh-less skull gives the perfect view of the human bone structure. Cast in PVC from a real human skull, it details bone, blood vessels, and the...
fromA. afarensistoHomo heidelbergensis, and within laterHomo. And finally,Schroeder and Ackermann (2017)used a combination of approaches to assess the relative roles of genetic drift and natural selection in the evolution ofHomoskull morphology, finding that genetic drift was widespread across much of...
The maximum principal strains measured in the skull bone are presented in Table 3. A threshold of 1.50% strain Trajectories and kinematics The trajectories of the simulated impact and the corresponding experimental impacts are presented in Figure 5. The 2-dimensional trajectories are presented relative...
Skin models, complicated skeletons (pelvis, ribcage, skull, and spine), and simple skeletons (tibia, femur, and humerus) have been analyzed separately. The personalized model’s geometric accuracy rises with landmarks after mesh morphing. However, too many landmarks will impede mesh morphing, ...
Researchers used bones of the Olduvai Hominid to reconstruct the Homo habilis skull, with the transparent parts based on a cranium from Kenya. (Image credit: Philipp Gunz, Simon Neubauer & Fred Spoor) The extinct human species long thought of as the earliest known member of the human family...
