Textbook Question
Chapter 10, Problem 1CCS
45-Year-Old Female with Motor Nerve Damage
In Chapters 7 and 8, you met Kayla Tanner, who suffered a dislocated right hip in a car accident. Six weeks later, Mrs. Tanner was still unable to walk or run without hip pain, and had weakness in flexion at the knee, excessive foot inversion and plantar flexion, and significant “foot drop” (the inability to dorsiflex the foot).
Electromyography (measurement of muscle electrical activity) and nerve conduction studies (measurement of the speed of nerve impulses) revealed sciatic nerve damage, most likely a result of the nerve being compressed when the hip was dislocated. This large nerve innervates many lower limb muscles. Since her surgery, Mrs. Tanner has been undergoing intense physical therapy and has shown significant improvement.
1. During her initial visit, the physical therapist focused on the prime movers and synergists of the hip, knee, and ankle. What are "prime movers" and "synergists”?

Motor innervation of the leg proper comes predominantly from the _____ plexus.
A 20-year-old man complained that he was unable to raise his right upper limb. He held it limply at his side with his forearm and hand pronated. During questioning by the physician, he stated that he had been thrown from his motorcycle approximately 2 weeks previously and that he had hit his shoulder against a tree. He also recalled that his neck felt sore shortly after the accident.
Physical Examination: On examination it was found that the patient was unable to flex, abduct, or laterally rotate his arm. In addition, he lost flexion of the elbow joint. A lack of sensation was detected on the lateral surface of his arm and forearm. The physician requested radiographs of the cervical and pectoral girdle regions.
Radiology Report: No fractures are seen in the cervical region, pectoral girdle, and proximal part of the humerus.
Diagnosis: Injury of nerves derived from the brachial plexus.
Using your anatomical knowledge of the nerve supply to the upper limb, discuss the…
