Masseter Muscle: Location, Actions, and Trigger PointsSee the
16.1). A pair of monopolar electromyography (EMG) needle electrodes (in six patients) or a pair of hook wire electrodes (in four patients) were introduced at this location for electrically stimulating the masseteric nerve (Video 16.1 – supplementary material on the web). Muscle responses were ...
putative relationship between structure and function in the human masseter muscle as a basis for understanding function and dysfunction in human jaw muscles.In the first experiment single motor unit (SMU) activity was recorded from pairs of recording sites distributed throughout the masseter muscle. In...
Methods To develop the learning model for masseter muscle volume, we used manually extracted data from CT images of 277 patients. We established the association between manually extracted masseter muscle volume and the life expectancy of oral cancer patients. Additionally, we compared the ...
In that study, the latency and duration of ES2 were similar in the temporalis and masseter muscles of single subjects, but the inter-individual variability of the duration was high. A more recent study8 found that local experimental muscle pain, induced by injecting hypertonic saline into the ...
Question: The muscle pointed is: a. depressor anguli oris b. levator labii superioris c. masseter d. orbicularis oris Facial Expression Smiling is considered a facial expression and is typically interpreted as a happy expression. There is much debate whether this...
Objective Temporomandibular disorders are frequently treated using botulinum neurotoxin, which may relieve pain by limiting masseter muscle function and reducing size. Masseter size is generally measured by direct visualization/palpation. Muscle size can be objectively and noninvasively imaged using 2-...
The activity reduction decreased with increasing distance from the location of the infusion. The results support the idea that the strategy of differential activation protects the injured muscle while simultaneously maintaining optimal function.doi:10.1034/j.1600-0722.2002.11198.xTürp, Jens C...
We suggest that trigeminal premotor interneurons with projections to the NVmot-mass fall into two broad categories, those with inputs from the IAN and/or ION and those with inputs from the MassN, possibly muscle spindle afferents, and no neuron receiving inputs from both....
