Quantitative assessment of masticatory muscles based on skull muscle attachment areas in Carnivora

open access: yesThe Anatomical Record, EarlyView.
Abstract Masticatory muscles are composed of the temporalis, masseter, and pterygoid muscles in mammals. Each muscle has a different origin on the skull and insertion on the mandible; thus, all masticatory muscles contract in different directions. Collecting in vivo data and directly measuring the masticatory muscles anatomically in various Carnivora ...

Ectopic impacted third molar in the mandibular condyle associated with a dentigerous cyst: A case report

open access: yesKouqiang hemian waike zazhi
Ectopic teeth are commonly found in the maxillary sinus and nasal cavity, while impacted third molars in the mandible are relatively rare. Cases of ectopic impaction of the third molar occurring in the condyle accompanied by dentigerous cysts are even ...

The TGFβ type I receptor TGFβRI functions as an inhibitor of BMP signaling in cartilage. [PDF]

open access: yes, 2019
The type I TGFβ receptor TGFβRI (encoded by Tgfbr1) was ablated in cartilage. The resulting Tgfbr1 Col2 mice exhibited lethal chondrodysplasia. Similar defects were not seen in mice lacking the type II TGFβ receptor or SMADs 2 and 3, the intracellular ...

The oldest Brazilian snakes from the cenomanian (Early Late Cretaceous) [PDF]

open access: yes, 2014
South American Mesozoic snake diversity is mostly represented by genera from the Cenomanian (Najash), Santonian- Campanian (Dinilysia), and Campanian-Maastrichtian (Alamitophis, Patagoniophis, Rionegrophis, and Australophis) of Patagonia, Argentina.

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

open access: yesThe Anatomical Record, EarlyView.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.

Three-dimensional condyle changes and bone remodeling of skeletal class Ⅲ patients treated with bimaxillary surgery

open access: yesKouqiang hemian waike zazhi
[Objective:] To evaluate the effectiveness of three-dimensional (3D) reconstruction software in assessing condyle changes after orthognathic surgery and to clarify 3D changes of condyles and bone remodeling after bimaxillary surgery for skeletal class Ⅲ ...

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

open access: yesThe Anatomical Record, EarlyView.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...
