In voluntary contraction of the skeletal muscles, the muscle potential ranges from ________(a) 50 uV – 5 mV(b) 50 mV – 5 V(c) 0.05 uV – 2 mV(d) 50 mV – 500 mV |

Answer» The correct answer is (a) 50 uV – 5 mV To explain I would say: In voluntary contraction of the skeletal muscles, the muscle potential ranges from 50 uV – 5 mV and duration from 2 to 15 ms. The values vary with the anatomic position of the muscle and the size and location of the electrode. In a relaxed muscle there are no action potentials. |
