Measures the electrical activity of muscles.
A
Electromyograph
B
Electroencephalograph
C
Electrooculograph
D
Electrocardiograph
Explanation: 

Detailed explanation-1: -Electromyography (EMG) measures muscle response or electrical activity in response to a nerve’s stimulation of the muscle. The test is used to help detect neuromuscular abnormalities. During the test, one or more small needles (also called electrodes) are inserted through the skin into the muscle.

Detailed explanation-2: -Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons). EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission.

Detailed explanation-3: -The EMG signal is a biomedical signal that measures electrical currents generated in muscles during its contraction representing neuromuscular activities. The nervous system always controls the muscle activity (contraction/relaxation).

Detailed explanation-4: -What is an EMG (electromyography)? Electromyography (EMG) is a diagnostic test that evaluates the health and function of your skeletal muscles and the nerves that control them. It’s one form of electrodiagnostic testing.

Detailed explanation-5: -An electroencephalogram (EEG) is a test that measures electrical activity in the brain using small, metal discs (electrodes) attached to the scalp. Brain cells communicate via electrical impulses and are active all the time, even during asleep. This activity shows up as wavy lines on an EEG recording.
