Variability of jaw muscles in Tunisian street dogs and adaptation to skull shape

The Anatomical Record, EarlyView.
Abstract The impact of artificial selection on the masticatory apparatus of dogs has been poorly studied, and comparative data with dogs subjected to more natural constraints are lacking. This study explores the jaw musculature of Tunisian street dogs, which are largely free from the influence of breed‐specific selection.

Mammalian Masticatory Muscles: Homology, Nomenclature, and Diversification [PDF]

Integrative and Comparative Biology, 2011
There is a deep and rich literature of comparative studies of jaw muscles in mammals but no recent analyses employ modern phylogenetic techniques to better understand evolutionary changes that have occurred in these muscles. In order to fully develop and utilize the Feeding Experiments End-user Database (FEED), we are constructing a comprehensive ...

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 ...

FEATURES OF EMG-ACTIVITY OF MASTICATORY MUSCLES OF YOUNG ADULTS OF DIFFERENT SOMATOTYPES

Вісник проблем біології і медицини, 2020
The study of the functioning peculiarities of the components of orofacial system needs considerable attention. It is important to understand the individual characteristics of the masticatory muscles in accordance with the somatotype, which allows to ...

Activity of the masticatory muscles and occlusal contacts in young adults with and without orthodontic treatment.

BMC Oral Health, 2015
Symmetry evaluation of the craniofacial complex generally involves models of mandibular movement and masticatory muscle activity, especially during the development of the craniofacial complex.

Linking individual variation in facial musculature to facial behavior in rhesus macaques

The Anatomical Record, EarlyView.
Abstract Facial expression is a key component of primate communication, and primates (including humans) have a complex system of facial musculature underpinning this behavior. Human facial musculature is highly variable across individuals, but to date, whether other primate species exhibit a similar level of inter‐individual variation is unknown ...

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 ...

Optogenetic activation of serotonergic neurons changes masticatory movement in freely moving mice

Scientific Reports
The serotonergic system modulates the neural circuits involved in jaw movement; however, the role of serotonin (5-HT) neurons in masticatory movement remains unclear.

Multiparameter Electromyography Analysis of the Masticatory Muscle Activities in Patients with Brainstem Stroke at Different Head Positions

Frontiers in Neurology, 2017
The performance of the masticatory muscle is frequently affected and presents high heterogeneity poststroke. Surface electromyography (EMG) is widely used to quantify muscle movement patterns.
