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 serves to move the bone or structure. A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable. ( https://medlineplus.gov/ency/imagepages/19089.htm) 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) tibia fibula and talus form the joint of the ankle. I believe Jill strained her ankle because she was able to continue playing the game. A strain is when the muscle or tendon is stretched. A sprain is when a ligament is stretched or torn. (http://www.mayoclinic.org/diseases- conditions/sprains-and-strains/basics/definition/con-20020958) 3. What are the four major ligaments of the knee along with their individual function in respect to the femur? (1 point) Anterior cruciate ligament, Posterior cruciate ligament, medial collateral ligament, lateral collateral ligament. The ACL controls rotation and forward movement of the tibia,. The PCL is located on the middle of the knee and controls backward movement of the tibia. The MCL is located in the center of the knee and gives stability to the knee. The LCL gives stability to the outer knee. (http://www.hopkinsmedicine.org/healthlibrary/test_procedures/orthopae dic/knee_ligament_repair_92,p07675/) 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 were the trainer I would see her reddened knee and it would be swollen. The trainer put ice on her knee right away in order to reduce swelling in the knee. 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) The positive Lachman’s test signifies indicate ACL injury. These are other types of orthopedic tests a physician may use to confirm a ligament injury: Apprehension sign, Anterior Drawer Test. An X-ray and MRI may also be used to confirm a diagnosis.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
