[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 ...

[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).

The silent period duration of the masticatory muscles
The Journal of Prosthetic Dentistry, 1989This study was conducted to determine whether the reflex activity of the masticatory muscles is altered in prostheses wearers. The electromyographic silent period was measured on an oscilloscope screen. Thirty subjects were examined. Five subjects had natural dentitions. Twenty-five partially edentulous subjects wore removable prostheses.

Growth Patterns of the Rabbit Masticatory Muscles
Journal of Dental Research, 1990The post-natal growth of the masticatory muscles in the rabbit was examined. By means of anatomical dissection and measurement, total muscle length, muscle fiber length, and muscle weight were determined in animals varying in age between one week and 36 months and exhibiting a 50-fold weight increase.

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.

Growth and allometry in primate masticatory muscles
Archives of Oral Biology, 1984A study of the dry weight of primate and non-primate masticatory musculature permitted possible allometric and ontogenetic influences on this musculature to be explored. Using weight as an indicator of adult body size, all of the masticatory muscles examined (anterior temporalis, posterior temporalis, masseter, medial pterygoid, lateral pterygoid ...

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 V. Geometry of the masticatory muscles and cranial morphology].
Nederlands tijdschrift voor tandheelkunde, 2002Studies focussed on the interactions between masticatory function and the variation in craniofacial height have received an important impulse by the availability of non-invasive imaging techniques like CT and MRI. These techniques allow for in vivo determination of the cross-sectional area and spatial orientation of the human jaw muscles. In recent MRI

[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.
