Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint
The Anatomical Record, EarlyView.Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),

Local Ridge Formation and Domain Delimitation in Aggregation-Diffusion Equations [PDF]
arXivOn the carapace of turtles such as Mauremys japonica, raised linear structures called keels form along the midline during embryonic development. This study investigates the underlying mechanisms of keel formation and domain delimitation on the carapace using a theoretical framework based on aggregation-diffusion equations. In this model, outward tissue

Early life functional transitions impact craniofacial morphology in osteogenesis imperfecta
The Anatomical Record, EarlyView.Abstract Early life behaviors have a profound role in shaping adult craniofacial morphology. During early life, all mammals undergo the dynamic transition from suckling to mastication, a period coinciding with rapid cranial biomineralization. Osteogenesis imperfecta (OI), a genetic disorder that impacts the production of type I collagen, disrupts ...

The Anatomical Record, EarlyView.Abstract Modularity and integration are key developmental properties and have remained central in evo‐devo research because of how they relate to evolvability. While modularity and integration have commonly been assessed with landmark‐based geometric morphometrics (GMM), other methods such as anatomical network analysis (AnNA) are increasingly being ...

A Probabilistic Model of Bilateral Lymphatic Spread in Head and Neck Cancer [PDF]
arXivCurrent guidelines for elective nodal irradiation in oropharyngeal squamous cell carcinoma (OPSCC) recommend including large portions of the contralateral lymph system in the clinical target volume (CTV-N), even for lateralized tumors with no clinical lymph node involvement in the contralateral neck.

The 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 ...

SEVERE CROWDING WITH UPPER MIDLINE SHIFT ASSOCIATED WITH AN SUPERNUMERARY TOOTH: A CASE REPORT
Romanian Journal of Medical and Dental Education, 2018 Supernumerary tooth represents a developmental anomaly that consists in duplication of tooth in the normal series. The presence of a supernumerary tooth may result in the appearance of aesthetic or functional problems in the dento-maxillary system.

The Anatomical Record, EarlyView.Abstract Mysticetes, or baleen whales, have an air sac on the ventral surface of the larynx known as the “laryngeal sac.” The primary hypothesis regarding this structure's function is that it is involved in sound production. However, several other functions have been proposed, including air recycling, air storage, and even buoyancy control.
