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 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.

Myositis Ossificans Traumatica of the Masticatory Muscles
Journal of Craniofacial Surgery, 2012Myositis ossificans traumatica (MOT) is a disease in which muscular ossification develops following trauma. Almost all cases of MOT are found in skeletal muscle. The authors report in a 39-year-old man MOT involving several muscles in the head and neck, namely, bilateral masseter muscles, the left temporal muscle, the left lateral pterygoid muscle, and

[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.

[Myalgia of the masticatory muscles].
Schmerz (Berlin, Germany), 2009Masticatory muscle pain can be regarded as a regional manifestation of musculoskeletal disorders similar to those observed in other body regions. Along with temporomandibular joint pain and some painless disturbances related to mandibular mobility they are subsumed under the term temporomandibular disorders (TMD).

Tendon entheses of the human masticatory muscles
Anatomy and Embryology, 2000Tendons attach to the limb skeleton via chondral-apophysary or periosteal-diaphysary entheses. It was the aim of the present study to investigate the tendon entheses of the temporal, the masseter, as well as the medial and lateral pterygoid muscles, considering the biomechanics and the mode of osteogenesis at the attachment sites.

Craniomandibular disorders and masticatory muscle function
European Journal of Oral Sciences, 1992The heading craniomandibular disorder covers a wide range of abnormal and pathologic conditions accompanied by orofacial pain and impaired mandibular function, the masticatory muscles and the temporomandibular joints being the structures most frequently involved.

[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 ...

The histochemistry of reactive masticatory muscle hypertrophy
Muscle & Nerve, 1996There are two types of hypertrophy of the muscles of mastication in man: reactive hypertrophy, the more common form; and nonreactive enlargements-myositic, genetic, myopathic, and idiopathic. Reactive hypertrophy develops when the masticatory muscle workload is increased by local bone and dental disorders; such triggers are not powerful but act over ...

[Masticatory muscles. Part II. Functional properties of the masticatory muscle fibers].
Nederlands tijdschrift voor tandheelkunde, 2002The masticatory muscles in human beings and in other mammals show a number of specific adaptations. Their muscle fibres contain at least four different isoforms of myosin heavy chain (MHC) and many fibres express more than one kind simultaneously. This implicates a continuous range of fibre contraction speeds for these muscles.
