Masseter Muscle: Location, Actions, and Trigger PointsSee the
It was concluded that: 1) radiopaque muscle markers are a valuable tool for analysis of muscle growth and alteration of muscle location; 2) the masseter muscle in the rhesus monkey undergoes elongation, probably due to addition of sarcomeres at the fiber-tendon junctions; and 3) posterior ...
The length of the digastric muscle belly is 55.3 +/- 1.1 mm. The length of the geniohyoid muscle is 44.5 +/- 0.9 mm. The distance between the centers, where the digastric muscle are fixed on the hypoglossal bone is 46.1 +/- 1.1 mm, and on the mandible--25 +/- 9 mm. The width...
The method combines a single motor unit (SMU) electromyographic (EMG) technique, magnetic resonance imaging, the 3-dimensional reconstruction of orofacial tissues, and a common reference system. SMU EMG activity can be recorded from different sites in the masseter muscle, and the location of these...

In addition, muscle function has been shown to have a direct effect on the craniofacial structures, depending on the anatomical location and growth direction of the muscles in question [11]. A study looking into rat craniofacial growth found that masticatory function tended to have a more ...
