Question

Quizplus · Accepted Answer

Electromyography (EMG) involves the use of needles inserted into muscles to measure the electrical activity across muscle membranes. A muscle biopsy is a procedure to remove a small piece of muscle tissue for examination, while lactic dehydrogenase and creatine phosphokinase are blood tests used to assess muscle damage or injury.
