Rethinking brachycephaly: Anatomical implications and health considerations in lagomorphs

The Anatomical Record, EarlyView.
Abstract Brachycephaly in domestic rabbits is increasingly perceived by welfare organizations as associated with significant health complications, particularly oral pathologies. Despite this perception, comparative anatomical research into rabbit brachycephaly is limited compared to that of dogs and cats, compelling an in‐depth examination of its ...

Morphometric analysis of the mandibular foramen of cats (Felis catus, Linnaeus 1758) with no defined breed / Análise morfométrica do forame mandibular em gatos domésticos (Felis catus,Linnaeus 1758) sem raça definida

Bioscience Journal, 2009
Objetivou-se, avaliar morfometricamente o forame mandibular, em gatos sem raça definida, visando ainda estabelecer de forma mais precisa sua topografia, com vistas a oferecer subsídios para um bloqueio anestésico local mais efetivo do nervo alveolar ...

Placa bloqueada e uso de antimicrobiano local no tratamento de fratura mandibular exposta em equino

Medicina Veterinária, 2020
A mandíbula é o osso da cabeça mais comumente fraturado nos equinos, sendo normalmente relacionada ao histórico de trauma. O objetivo deste relato é descrever um caso de fratura exposta de mandíbula em um equino com exsudação serossanguinolenta advinda ...

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

The Anatomical Record, EarlyView.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

The Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

The Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

Previously undocumented regional variability in crab‐eating macaque skull sexual dimorphism and its implications for biological and morphometric studies

The Anatomical Record, EarlyView.
Abstract In a large sample of adult crab‐eating macaques, we quantified sexual dimorphism in size, shape, and covariance across the whole skull and among anatomical regions of the cranium and mandible. All regions showed significant mean sex differences, but the magnitude of size and shape dimorphism varied substantially.

Carcinoma mucoepidermoide central de la mandíbula, en un paciente con displasia fibrosa quística mandibular

Acta Médica Costarricense, 2006
El carcinoma mucoepidermoide de glándula salival es un tumor frecuente; constituye el 15% de los tumores de dicha estructura. Sin embargo, en la mandíbula son mucho menos frecuentes (menos de 200 casos reportados) y se le conoce como carcinoma ...

Pelvic morphology and body size in relation to the preauricular sulcus: Evidence from medieval to modern Iberia

The Anatomical Record, EarlyView.
Abstract The preauricular sulcus has long been debated as a pelvic feature variably attributed to obstetric stress, ligamentous traction, and broader biomechanical processes. To clarify its determinants, we analyzed 409 adult individuals from three archeological and one early modern skeletal collection from the Iberian Peninsula, integrating graded ...

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

The Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,
