Abstract :

In this study, we try to present a complete model of skeletal muscle, with the aim of expressing it's behavior in a precise manner. This model is presented with considering the role of sensory receptors in muscle function. Muscle spindle and Golgi tendon receptors provide information on length changes and muscle force, respectively . Then this information is sent to the central nervous system for final decision making. In this study, adaptive combination of the Spindle and Golgi tendon afferents Due to the changes in their level of activity and the force produced in the muscle under different functional conditions is suggested. Considering the control feedbacks of the afferents in the presented model can optimize the precise behavior of the muscle under different loads and eliminate the limitations of previous models. The results of the proposed model according to the precise modeling of sensory receptors (Muscle spindle and Golgi tendon) have been consistent with the experimental results of muscle activity. This model can be used to predict muscle's behavior in preventing muscular nervous system damage, as well as the design of artificial muscles and different prostheses.
