Textbook Question
Chapter 10, Problem 3CCS
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.
3. + NCLEX-Style Mrs. Tanner's difficulty flexing her leg at the knee is most likely due to problems with:
a. The gastrocnemius
b. The quadriceps femoris
c. The biceps femoris
d. The biceps brachii

For this set of questions you will need to stand up from the chair you are sitting in,
and then sit back down. Do this slowly so that you can pay attention to what is
happening, and if necessary feel the tone of the muscles in your legs as your
standing and sitting (If you are lying down or standing start from a seated position,
then stand, then sit).
a) During the standing phase, what function is being carried out at the hip joint?
b) What are the prime movers (agonists) that are responsible for this particular
movement (Hint: You should be able to feel them activated)?
c) During the standing phase, what function is being carried out at the knee joint?
d) What are the prime movers (agonists) that are responsible for this particular
movement (Hint: You should be able to feel them activated)?
e) As you sit back down, you realize that some of the same muscles activated during
standing are also active when going from standing to sitting. Explain?
The pectoralis major muscle is innervated by the lateral pectoral nerve and axillary nerve.
True
False
Given the following diseases/conditions, relate them to the events that take place in the neuromuscular junction. Identify the specific cause and the pathologic manifestations of such conditions.
Myasthenia gravis
Lambert-Eaton Syndrome
Neuromyotonia
2. In 3-4 sentences compare and contrast the various types of muscle contraction (See attached picture) and be able to give at least an example for each. What type of contraction causes change in length of muscle fibers? Which type does not result to movement?

- 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.

His pain is increased when he tries to activate the shoulder by initiating external rotation and abduction. The man’s major complaint is that he is unable to comb his hair and brush his teeth without pain as he cannot maintain his arm in an elevated position for more than a few seconds. At the hospital, the doctor ordered an x-ray and gave him an injection of local anesthetic.
