Module 06 Case Study: Articulations and Nerve Tissue Part I— “Jill” Questions 1. What is the difference between a tendon and ligament? (1 point) Tendons bind muscle to bone, and ligaments bind bone to bone. A sprain is an extended and/or torn ligament, the band of connective tissue that connects the end of one bone with another bone. Ligaments support and stabalize the an individuals joints. A strain is an injury that occurs to a muscle and/or tendon. Tendons are fibrous cords of tissue, which connect muscles to bone (Muscle of the Foot and Ankle, n.d). 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 ankle articulation consists of three bones that are the tibia, fibula and the talus. A sprain is an injury that involves the tearing or stretching of a ligament or a joint capsule. Sprains happen when a joint is forced past its regular range of motion. I believe Jill sprained her ankle because there was severe ankle pain, swelling, bruising and Jill could not walk after the second incident. A strain is an injury that involves the tearing or stretching of a muscle and or tendon structure. An acute strain of the muscle or tendon structure happens at the connection where the muscle is becoming a tendon. These strains occur when a muscle is stretched or suddenly is contracted (Sutton, n.d). 3. What are the four major ligaments of the knee along with their individual function in respect to the femur? (1 point) The medial Collateral Ligament also known as the MCL is a band that runs in between the inner surfaces of the femur and the tibia. It endures forces acting starting on the outer surface of the knee which is called valgus forces, this stops the knee from collapsing inwards. The MCL has two parts; an inner part that
