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

open access: yesThe 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

Superolateral extracapsular dislocation of the mandibular condyle: Review of the literature and report of two cases

open access: yesOral and Maxillofacial Surgery Cases, 2019
Trauma to the temporomandibular joint may cause one of several injuries amongst which is the dislocation of the mandibular condyle. Several aetiological factors result in condylar dislocation, and although there are global variations, road traffic ...

Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

open access: yesThe Anatomical Record, EarlyView.
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Osteochondroma involving mandibular condyle

open access: yesJournal of Indian Academy of Oral Medicine and Radiology, 2017
Osteochondroma is defined as an osteocartilagenous exostosis with cartilage capped exophytic lesion that arises from the bone cortex. It is a slow growing benign tumor that is rarely seen in the maxillofacial region.

PTHrP regulates chondrocyte maturation in condylar cartilage [PDF]

open access: yes, 2003
PTHrP is a key factor regulating the pace of endochondral ossification during skeletal development. Mandibular advancement solicits a cascade of molecular responses in condylar cartilage.

Ontogenetic changes and sexual dimorphism in the cranium and mandible of the Atlantic walrus (Odobenus rosmarus rosmarus L.)

open access: yesThe Anatomical Record, EarlyView.
Abstract Walruses have been an important subsistence and cultural resource for humans and have been exploited for millennia across their distribution. This exploitation has contributed to severe declines in several populations and local extirpations.
