Tandem muscle-spindle in the masseter muscle of mice.

Muscle spindle afferent input to motoneurons in human masseter.

The H-reflex response in large and small single motor units in human deep anterior masseter was studied to investigate the distribution of muscle spindle afferents onto masseter motoneurons. We found that only the larger units displayed H-reflex responses. This indicates preferential distribution of muscle spindle input onto large motoneurons or a skewed distribution of tonic presynaptic inhibi...

Assessment of the Potential Role of Muscle Spindle Mechanoreceptor Afferents in Chronic Muscle Pain in the Rat Masseter Muscle

BACKGROUND The phenotype of large diameter sensory afferent neurons changes in several models of neuropathic pain. We asked if similar changes also occur in "functional" pain syndromes. METHODOLOGY/PRINCIPAL FINDINGS Acidic saline (AS, pH 4.0) injections into the masseter muscle were used to induce persistent myalgia. Controls received saline at pH 7.2. Nocifensive responses of Experimental r...

Intramuscular hemangioma of masseter muscle: A report of unique case

BACKGROUND AND AIM: Even though hemangiomas are prevalent tumors in the region of head and neck, they are comparatively rare inside the mouth and less frequently detected by dental professionals. Therefore, the aim of this case report is to present such a rare variation of hemangioma manifested within the substance of the masseter muscle.CASE REPORT: We report a unique case of intramuscular hem...
