Human jaw movement in mastication and speech.
The study of jaw movement in humans is a primary source of information about the relationship between voluntary movement and more primitive motor functions. This study focused on the geometric form of the velocity function, as measured by linear voltage displacement transducer. Movement amplitudes, maximum velocities and durations were greater in mastication than in speech. Nevertheless, there ...
متن کاملA dynamic model of jaw and hyoid biomechanics during chewing.
Our understanding of human jaw biomechanics has been enhanced by computational modelling, but comparatively few studies have addressed the dynamics of chewing. Consequently, ambiguities remain regarding predicted jaw-gapes and forces on the mandibular condyles. Here, we used a new platform to simulate unilateral chewing. The model, based on a previous study, included curvilinear articular guida...
متن کاملPutative feed-forward control of jaw-closing muscle activity during rhythmic jaw movements in the anesthetized rabbit.
When a thin plastic test strip of various hardness is placed between the upper and lower teeth during rhythmical jaw movements induced by electrical stimulation of the cortical masticatory area (CMA) in anesthetized rabbits, electromyographic (EMG) activity of the masseter muscle is facilitated in a hardness-dependent manner. This facilitatory masseteric response (FMR) often occurred prior to c...
متن کاملSuppression of movement disorders by jaw realignment.
It has been estimated that over 20% of adults have, or have had, internal derangement of the TMJ [3]. An internal derangement of the TMJ occurs when the cartilaginous disc that lies on the superior surface of the condyle becomes displaced from its normal location. In many cases of TMJ internal derangement, the auriculotemporal nerve (a small branch of the mandibular nerve) can become drawn into...
متن کاملJaw movement in people with Parkinson's Disease.
UNLABELLED This study aimed to characterize the amplitude and speed of isolated jaw movements and chewing using electrognathography in a volunteer and to compare these data with those of two other Parkinson Disease (PD) subjects, differentiated by the motor characteristics. METHOD The 3 participants were divided into three categories: one with 1 non-PD volunteer, a second category with 1 volu...
