Physiology of Skeletal Muscle Contraction

Physiology of Skeletal Muscle Contraction . The Muscle Action Potential ( AP ) . Muscle RMP = -90 mV ( same as in nerves ) . Duration of AP = 1-5 ms ( longer duration than nerve AP , which is usually about 1 ms ) . Conduction Velocity = 3-5 m/s ( slower than big nerves ) .
