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 کاملNumerical modeling of human mastication, a simplistic view to design foods adapted to mastication abilities
The human diet contains a large variety of aromas, tastes and textures. The latter is particularly important since it determines whether foods are difficult to process orally and thus can be one source of food avoidance. It has also been reported in recent literature that food texture was a main driver for satiation processes and thus it is of interest for the food manufacturing industry to be ...
متن کاملInfluence of age on adaptability of human mastication.
The objective of this work was to study the influence of age on the ability of subjects to adapt mastication to changes in the hardness of foods. The study was carried out on 67 volunteers aged from 25 to 75 yr (29 males, 38 females) who had complete healthy dentitions. Surface electromyograms of the left and right masseter and temporalis muscles were recorded simultaneously with jaw movements ...
متن کاملFrom Jaw Tracking towards Dynamic Computer Models of Human Mastication
In this paper, we enhance the model of the human masticatory system presented in [1] by incorporating prescribed movements of the mandible during a chewing cycle. To obtain realistic descriptions of such movements, we have developed a custom-made brace that allows us to use a motion capturing system typically applied to human movement and gait analysis. In this paper, we give a brief descriptio...
متن کاملMastication and acid secretion.
The gastric acid response and the buffer capacity of the stomach were measured in 30 control subjects and 22 duodenal ulcer patients in response to a masticatory (solid) and a non-masticatory (homogenized) meal having the same chemical composition. The peak acid output values were equal after a masticatory and after a non-masticatory diet in control subjects (masticatory 18.1 +/- 1.2, non-masti...
