Which is the process of recording the electrical potential of skeletal muscles and nerves supplying them by inserting small needle electrodes into the muscles?
EMG
The correct answer is EMG.
Electromyography (EMG) records the electrical activity of skeletal muscles (and, with nerve conduction studies, the nerves supplying them) using needle electrodes inserted into the muscle. It helps differentiate myopathy from neuropathy and diagnose conditions like myasthenia gravis and ALS.
ECT (electroconvulsive therapy) is a treatment, not a recording; EEG records brain electrical activity from scalp electrodes; ECG records the heart's electrical activity from skin electrodes.
Short trick: Myo = muscle → Electro-MYO-graphy; Encephalo = brain (EEG); Cardio = heart (ECG).
