The EMG is a recording of: * The action potentials of the motor nerves supplying the muscle fibers. The action potentials of the innervated muscle fibers. The contractions of the innervated muscle fibers O The action potential of the pacemaker cells O The electrical activity in the sarcoplasmic reticulum
Watch this short video (http://openstaxcollege.org/l/facialnerve) to see an examination of the facial nerve using some simple tests. The facial nerve controls the muscles of facial expression. Severe deficits will be obvious in watching someone use those muscles for normal control. One side of the face might not move like the other side. But directed tests, especially for contraction against resistance, require a formal testing of the muscles. The muscles of the upper and lower face need to be tested. The strength test in this video involves the patient squeezing her eyes shut and the examiner trying to pry her eyes open. Why does the examiner ask her to try a second time?
if 2 clenches produce a reponse the excat same force of contration would the emg reoding also have to be the same response. Why or why not

Did you get a measurable twitch with a stimulus of 0 mA? What does this tell you about thenumber of muscle fibers contracting at this stimulus current?
Does the EMG represents the AP of the muscle or the AP reached to the muscle by the nerve ? * O AP of the muscle O AP of the nerve O Both
