Module 06 Case Study: Articulations and Nerve Tissue

Module 06 Case Study: Articulations and Nerve Tissue Part I— “Jill” Questions 1. What is the difference between a tendon and ligament? (1 point) A Tendon is a strong collagen fibrous tissue that attaches muscle to a bone. A Ligament is a flexible connective fibrous tissue that connects bones to bones, cartilage or holds together a joint. 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) The bones that form the articulation joint of the ankle are fibula, tibia and the talus. It seems that she most likely sprained her ankle. It said that she twisted her ankle, most likely stretching or tearing ligaments in her ankle. A sprain is when you stretch or tear ligaments. A strain is the stretching or tearing of muscle or tendons. 3. What are the four major ligaments of the knee along with their individual function in respect to the femur? (1 point) The four major ligaments of the knee are the anterior cruciate ligament, posterior cruciate ligament, medial collateral ligament and the lateral collateral ligament. With the cruciate ligaments they control the forward and backward mobility and how far forward and back the knee is able to go without being sprained. In addition the collateral ligaments control the movements side to side and how far to go without being sprained. 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) If I was the trainer that initially saw Jill after her fall, I would have probably viewed her knee and saw that it was irritated and inflamed. You would put ice on her knee to try and reduce the inflammation/swelling. 5. What did a positive Lachman’s test signify? What are some of the other orthopedic tests the doctor most likely performs on Jill’s knee? (1 point) A Lachman’s test signifies an injury to the ACL. Other orthopedic tests the doctor will most likely perform are anterior/posterior drawer test and McMurray’s test. 6. W...
