Vedclass · Answer

(C) The resting membrane potential of a muscle fibre is typically around $-90 \, mV$.When a muscle fibre is stimulated, the membrane potential undergoes a rapid change, known as an action potential.The peak value of the action potential in a skeletal muscle fibre typically reaches approximately $+45 \, mV$ to $+50 \, mV$ due to the rapid influx of $Na^+$ ions.
