Muscle activity is related to a basic property of muscle – ability to acronyms or airway. However, the muscles could be reduced if the muscle tisue have not had yet and physiological properties such as excitability and conductivity.
The property of contractility is manifested in the ability of the muscles to a single or total (tetanic) contractions. The body always happen tetanic, relatively long muscle contractions, because they receive not alone the momentum and flow of rhythmic impulses from the Central nervous system (CNS), and each of them calls the new contractile effect before the end of the reduction from the previous pulse. However, in experimental conditions it is posible to reproduce single reduction; the graphic image Continue reading
