Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

The Anatomical Record, EarlyView.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

The Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

The buccal plug: A technique for management of focal cicatricial entropion and trichiasis

Indian Journal of Ophthalmology
Cicatricial entropion can be challenging to manage, and surgery may lead to anterior lamellar and focal lash loss or tarsal scarring. We describe a surgical technique to address focal cicatricial entropion that avoids conjunctival incisions and minimizes

In‐vitro puncture experiment using alligator teeth tracks the formation of dental microwear and its association with hardness of the diet

The Anatomical Record, EarlyView.
Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

Tubularized urethral reconstruction using a prevascularized capsular tissue prelaminated with buccal mucosa graft in a rabbit model

Asian Journal of Andrology, 2019
Tubularized graft urethroplasty fails largely because of inadequate graft take. Prefabrication of buccal mucosa lined flap has theoretical indications for constructing neourethra with an independent blood supply.

The lower jaw of Devonian ray‐finned fishes (Actinopterygii): Anatomy, relationships, and functional morphology

The Anatomical Record, EarlyView.
Abstract Actinopterygii is a major extant vertebrate group, but limited data are available for its earliest members. Here we investigate the morphology of Devonian actinopterygians, focusing on the lower jaw. We use X‐ray computed tomography (XCT) to provide comprehensive descriptions of the mandibles of 19 species, which span the whole of the Devonian

Quantitative criteria for improving performance of buccal DNA for high-throughput genetic analysis

BMC Genetics, 2012
Background DNA from buccal brush samples is being used for high-throughput analyses in a variety of applications, but the impact of sample type on genotyping success and downstream statistical analysis remains unclear.

Integrating mandibular evidence to assess morphological variation of the Australopithecus afarensis maxilla

The Anatomical Record, EarlyView.
Abstract Geometric morphometric analyses are used to explore variation of maxillary dental arcades of Australopithecus afarensis, expanding on the work of Hanegraef and Spoor, 2025 (Morphological variation of the Australopithecus afarensis maxilla.

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

The Anatomical Record, EarlyView.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...
