| Abstract: | Excitability parameters of m. digastricus muscle fibers were investigated in anesthetized (40 mg/kg of nembutal) rats 3-5 days after denervation. The number of fibers with high polarization level was increased as was the number of fibers with low and medium level in both bellies of m. digastricus. The differences in the level of polarization recorded in the muscle fibers of the abdominoposterior m. digastricus disappeared after denervation. It is suggested that denervation syndrome in m. digastricus deprived of spindle receptors was similar to that observed in other skeletal muscles. |
