Module 06 Case Study: Articulations and Nerve Tissue

Part I— “Jill” Questions

1. What is the difference between a tendon and ligament? (1 point)

2. What bones form the articulation (joint) of the ankle? Did Jill most likely sprain or strain her ankle? Explain your reasoning and the difference between the two? (1 point)

3. What are the four major ligaments of the knee along with their individual function in respect to the femur? (1 point)

4. If you were the trainer that initially saw Jill after her fall, describe what her knee probable looked at (Hint-inflammation). Why did the trainers put ice on her knee right away? (1 point)

5. What did a positive Lachman’s test signify? What are some of the other orthopedic tests the doctor most likely perform on Jill’s knee? (1 point)

6. Why didn’t the X-ray demonstrate (show) anything wrong with Jill’s knee? Why did the doctor order an MRI and what was the doctor’s reasoning to wait a week before doing the MRI? (1 point)

7. Besides damage to the ligament(s), what other anatomical structures could the MRI demonstrate (show) damage to? (1 point)

8. Describe the procedure of arthroscopic knee surgery. What should a patient expect after arthroscopic reconstructive ligament surgery- recovery time, strength/stability of knee, long-term complications? (1 point)

Part II— “Kathy” Questions

1. What components of the nervous system are involved in physical sensation? How does sensory impulse move throughout the body? (1 point)

2. What components of the nervous system are involved in skeletal muscle movement? How does motor impulse move throughout the body? What is a “motor unit”? (1 point)

3. What movements are involved in the action of standing up? What muscles need to contract to perform these actions? (1 point)

4. What are the different levels of organization of a muscle down to myofilaments? What is a “sarcomere” and how are its proteins organized?...
