APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -During a needle EMG, a needle electrode inserted directly into a muscle records the electrical activity in that muscle. A nerve conduction study, another part of an EMG, uses electrode stickers applied to the skin (surface electrodes) to measure the speed and strength of signals traveling between two or more points.

Detailed explanation-2: -The EMG is performed using an instrument called an electromyograph to produce a record called an electromyogram.

Detailed explanation-3: -Electromyography (EMG) and nerve conduction studies are tests that measure the electrical activity of muscles and nerves. Nerves send out electrical signals to make your muscles react in certain ways. As your muscles react, they give off these signals, which can then be measured.
