Morphology and Physiology of Masticatory Muscle Motor Units [PDF]

Critical Reviews in Oral Biology & Medicine, 2001
Motor unit territories in masticatory muscles appear to be smaller than territories in limb muscles, and this would suggest a more localized organization of motor control in masticatory muscles. Motor unit cross-sectional areas show a wide range of values, which explains the large variability of motor unit force output.

Electromyographic activity of masticatory muscles in women with osteoporosis [PDF]

Brazilian Dental Journal, 2009
The purpose of this study was to analyze the electromyographic (EMG) activity and the maximal molar bite force in women diagnosed with osteoporosis in the maxillary and mandibular regions, considering the habits and conditions that lead to development of generalized skeletal bone loss, including on face bones, can disturb the functional harmony of the ...

Functional Role of Suprahyoid Muscles in Bolus Formation During Mastication

Frontiers in Physiology, 2022
It still remains unclear how the suprahyoid muscles function in bolus formation during mastication. This study aimed to investigate the contributory role of the suprahyoid muscles during mastication.

Myosin Heavy-Chain Messenger Ribonucleic Acid (mRNA) Expression and Fibre Cross-Sectional Area in Masseter, Digastric, Gastrocnemius and Soleus Muscles of Young and Adult Rats

Biology, 2023
Different demands on the muscles of mastication may influence their functional profile (size and distribution of muscle fibre types), which may change during growth and maturation, potentially influencing craniofacial growth. The aim of this study was to

Depression and Resting Masticatory Muscle Activity [PDF]

Journal of Clinical Medicine, 2020
Background: The aim of this study was to determine the influence of moderate depression determined based on Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMDs) Axis II on the bioelectrical resting activity of temporal muscles and masseter muscles. Methods: The research participants were 68 healthy adult women. Of these, 46 people h (

Interactive Modelling of Volumetric Musculoskeletal Anatomy [PDF]

ACM Trans. Graph., Vol. 40, No. 4, Article 122. Publication date: August 2021, 2021
We present a new approach for modelling musculoskeletal anatomy. Unlike previous methods, we do not model individual muscle shapes as geometric primitives (polygonal meshes, NURBS etc.). Instead, we adopt a volumetric segmentation approach where every point in our volume is assigned to a muscle, fat, or bone tissue.

Sensory innervation of masseter, temporal and lateral pterygoid muscles in common marmosets

Scientific Reports, 2023
Myogenous temporomandibular disorders is associated with an increased responsiveness of nerves innervating the masseter (MM), temporal (TM), and lateral pterygoid muscles (LPM).
