- Watch this short video (http://openstaxcollege.org/l/facialnerve) to see an examination of the facial nerve usingsome simple tests. The facial nerve controls the musclesof facial expression. Severe deficits will be obvious inwatching someone use those muscles for normal control.One side of the face might not move like the other side. Butdirected tests, especially for contraction against resistance,require a formal testing of the muscles. The muscles of theupper and lower face need to be tested. The strength testin this video involves the patient squeezing her eyes shutand the examiner trying to pry her eyes open. Why does theexaminer ask her to try a second time?arrow_forward5) the facial nerve is the innervation for which muscles? a) buccinator,orbicularis oculi, depressor labii inferioris b) buccinator only c) buccinator and orbicularis oculi only d) masseter and buccinator e) masseter and orbicularis oculiarrow_forwardFor each of the following body regions, name the peripheral nerve that carries somatic motor fibers to most of the skeletal muscles: flexor surface of the arm flexor surface of the forearm extensor surface of the arm and forearm anterior thigh posterior thigh anterior leg posterior legarrow_forward
