ABSTRACT
15 male Wistar rats of 8 weeks old were used in this experment. After deeply anesthesia, the masseter muscles, digastric muscles, lateral pterygoid muscles were stimulated in the apartment that was made by us. The curves that express the relations of force-electronic stimulates were recorded and the constitutive equations of these muscles were given. When a single electronic signal stimulates the muscle, the respondence of the muscles can be expressed as F = A(e-alpha t - e-beta t) and the constant A, alpha, beta were determined. When the frequency of the electronic stimulation was higher than 3 Hz, the respondence was expressed as F = Ce-gamma/t + Dsin omega t and the constants C, D and gamma were determined. When the frequency of the electronic stimulation was thirty or higher, the tetanic convulsion occurred.
