Scaling functional patterns of skeletal and cardiac muscles: New non-linear elasticity approach [PDF]

arXiv, 2009
Responding mechanically to environmental requests, muscles show a surprisingly large variety of functions. The studies of in vivo cycling muscles qualified skeletal muscles into four principal locomotor patterns: motor, brake, strut, and spring.

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.

A Comparison of Ultrasonic Thickness of Masseter Muscle between Patients with Bruxism and Healthy People

Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2017
BACKGROUND AND OBJECTIVE: Evaluating the thickness of the masseter muscle is an important determinant of the health or illness of the muscle. Investigating changes in masseter muscle thickness due to its function on the temporomandibular joint plays a ...

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 ...

Real-time PCR detection of Toxoplasma gondii in tissue samples of wild boars (Sus scrofa) from southern Italy reveals high prevalence and parasite load. [PDF]

, 2019
Background: Toxoplasmosis is a zoonotic parasitic disease caused by Toxoplasma gondii, a widespread protozoan in the phylum Apicomplexa. In Europe, several studies have demonstrated the presence of the parasite in tissues of wild boars (Sus scrofa), but ...

Searching for the Grand Tack in Exoplanetary Data [PDF]

A&A 688, L6 (2024)
The grand tack model, more generally called the Masset and Snellgrove mechanism, is a planetary migration model whereby two giant planets via interactions with their natal disk migrated to larger orbital radii. While its relevance in our own Solar System remains in question, the fact that the Masset and Snellgrove mechanism is a general hydrodynamical ...

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 ...

Masseter muscle thickness in different skeletal morphology: An ultrasonographic study

Indian Journal of Dental Research, 2010
Background: The thickness of the masseter muscle during relaxation and contraction states was measured by ultrasonography. Subjects were classified according to their sagittal skeletal relationships.

Masticatory muscle activity evaluation by electromyography in subjects with zygomatic implants [PDF]

, 2017
Zygomatic implants are an alternative treatment in the rehabilitation of atrophic maxilla to promote stability in the stomatognathic system. The aim of this study was to compare the electromyographic (EMG) activity of masseter and temporalis muscles in ...
