Laboratory – Muscle Physiology A. MUSCLE TONUS Observations‚ Report and Conclusion: A. Define muscle tonus and give its importance * Muscle tonus refers to a state of slight muscular contraction maintained by synchronous impulses of low frequency‚ discharged by the spinal motor neurons. * Reflex in nature. * Muscle tonus is a small amount of tension in the muscle due to weak‚ involuntary contractions of its motor units. Muscle tonus is important in a sense that it governs the

factors affect muscle fatigue? Introduction: In this experiment muscles will be tested with weight‚ to see if weight is truly a factor in muscle fatigue. Muscle fatigue is the muscle’s ability to contract exert its normal strength due to physical stress upon it. The structure of a muscle include a thin layer called epimysium which surrounds the entire muscle‚ deeper to the epimysium is the perimysium. This layer contains fascicles which are bundles of muscle cells. In between the muscle cells are endomysium
