[Masticatory muscles. Part IV. The masticatory muscles do not work homogeneously].

Nederlands tijdschrift voor tandheelkunde, 2002
The 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.

Craniomandibular disorders and masticatory muscle function

European Journal of Oral Sciences, 1992
The 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 III. Biomechanics of the masticatory muscles].

Nederlands tijdschrift voor tandheelkunde, 2002
The 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.

[Masticatory muscles. Part I. Functional anatomy of the masticatory muscles].

Nederlands tijdschrift voor tandheelkunde, 2002
The 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 ...

Further histochemical studies on masticatory muscles

Journal of the Neurological Sciences, 1980
This 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.

[Myalgia of the masticatory muscles].

Schmerz (Berlin, Germany), 2009
Masticatory 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).

[Masticatory muscles. Part V. Geometry of the masticatory muscles and cranial morphology].

Nederlands tijdschrift voor tandheelkunde, 2002
Studies 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, 2002
The 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.

[Masticatory muscles. Part VI. Masticatory muscles and movement of the lower jaw].

Nederlands tijdschrift voor tandheelkunde, 2002
The movement paths of the kinematic center of the temporomandibular joint were recorded by means of a jaw movement recording system (OKAS-3D) under 3 conditions: 1. free open and close movements; 2. free opening and loaded closing movements (subjects closed against a small, manually applied, downward directed force on the chin); and 3.

Growth and allometry in primate masticatory muscles

Archives of Oral Biology, 1984
A 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 ...
