Further histochemical studies on masticatory muscles
Journal of the Neurological Sciences, 1980This paper describes a histochemical and histographic analysis of the masticatory muscles obtained from 78 early autopsy samples from subjects from 4 days to 87 years old. Five groups of muscles have been stuied: the temporalis, the medial and lateral pterygoid, the superficial bundle of the masseter and the mylohyoideus.

Biofeedback: Control of masticatory muscle spasm
Medical & Biological Engineering, 1976Electronic circuits designed to amplify masticatory electromyographic voltages are described in detail. The equipment activates a tape recorder during bruxing episodes. The recorded data subsequently being converted into numerical terms by an electronic pulse counter.

Traumatic myositis ossificans in masticatory muscles
Journal of Maxillofacial Surgery, 19863 cases of traumatic myositis ossificans circumscripta, located within the masticatory muscles are presented. Two of the lesions involved the masseter muscle, and exceptionally, 1 involved the temporalis muscle. Three pathognomonic histological zones, permitting the differential diagnosis of myositis ossificans from sarcomatous lesions, are described ...

Quantification of tenderness of masticatory muscle.
Nihon Hotetsu Shika Gakkai Zasshi, 1990As more dentists diagnose and treat the patient with temporomandibular disorders, muscle palpation has been recognized as a valuable diagnostic method. But this method was depended on sensibility and experience of the operator. The purpose of this study was to establish the quantification of muscle palpation by new pressure pain threshold apparatus ...

[Masticatory muscles. Part IV. The masticatory muscles do not work homogeneously].
Nederlands tijdschrift voor tandheelkunde, 2002The temporalis and masseter muscles have a complex architectural design with large attachment areas. As a consequence, each of these muscles is capable of producing a large number of mechanical effects. In addition, within each muscle the muscle fibres and sarcomeres undergo different excursions during jaw movements.

Association between tongue muscle strength and masticatory muscle strength
Journal of Oral Rehabilitation, 2018SummaryBackgroundThe tongue is responsible for compressing food against the palate and squeezing it into the pharynx during the oral preparatory phase of swallowing. Tongue pressure (TP), an indicator of tongue muscle strength, has been observed to decline with age; maximum occlusal force (MOF), an indicator of chewing ability, is correlated with TP ...

[Masticatory muscles. Part III. Biomechanics of the masticatory muscles].
Nederlands tijdschrift voor tandheelkunde, 2002The masticatory muscles are able to produce forces. These forces may cause movements of the lower jaw. Furthermore, they can be applied by the teeth for the generation of bite or chewing forces. During these kind of processes the temporomandibular joints will be loaded also.

A review of masticatory muscle function
The Journal of Prosthetic Dentistry, 1987Current reports of the actions of the major muscles of mastication are reviewed for clenching tasks in centric occlusion and eccentric jaw positions, mandibular opening, and unilateral chewing. The relationship of the mandible to the maxillae in the intercuspal position and, consequently, the relationship of the condyle to the fossa of the ...

[Masticatory muscles. Part I. Functional anatomy of the masticatory muscles].
Nederlands tijdschrift voor tandheelkunde, 2002The anatomical design of the jaw-closing and jaw-opening muscles is of importance for their capability to produce forces and displacements. The length of the sarcomeres is a major determinant for both force and shortening range. The maximal work, force and shortening range each muscle is capable of producing, are proportional to the architectural ...

Masticatory Muscle Pain Biomarkers
2017This chapter focuses on the potential role of biomarkers for masticatory muscle pain, i.e., myalgia. To date, no biomarkers have been identified that can be used clinically for diagnosis or treatment of myalgia of jaw muscles. There is evidence from microdialysis studies that intramuscular levels of glutamate and serotonin are elevated in patients with
