Question

The contraction of the skeletal muscles results in the generation of action potential in the individual muscle fibers. Record of this action potential is called ............

• A. ECG
• B. EMG
• C. EEG
• D. EKG

Hint:

\textbf{EMG} is used to study muscle health and function by recording electrical activity during contraction, not to be confused with ECG (heart) or EEG (brain).

Answer 1

The Correct Option is B

When a skeletal muscle contracts, an action potential is generated within the muscle fibers. To measure and record this electrical activity, the technique used is called Electromyography (EMG).
EMG involves inserting electrodes into the muscle tissue or placing them on the skin surface to detect the electrical signals generated by muscle cells during contraction.
ECG (Electrocardiogram) is used to record the electrical activity of the heart, while EEG (Electroencephalogram) records brain waves. EKG is simply another name for ECG, derived from the German term.
Hence, for muscle action potentials, the correct recording technique is EMG.
