Part I— “Jill” Questions

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

Tendons and Ligaments are both fibrous connective tissue within the body. The difference between the two is that tendons are the connective tissue that hold muscles to bones and other body structures, to assist in the body’s movement. Ligaments are a connective tissue that hold bones together in order to keep them more stable.

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)

There are three bones that form the joint of the ankle. These are the tibia, fibula and talus. Jill most likely sprained her knee and ankle due to the fact of her twisting and falling on it. Sprains are common injuries to the ankle and a strain is more common in the back and hamstring from contact sports. She was playing basketball which involves excessive twisting on the ligaments. A sprain is when the joint is moved out of its normal position causing it to pull or tear the ligaments. A strain is the overuse of a muscle and tendon or the excessive pulling or twisting of it.

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 in the knee are the Anterior Cruciate Ligament (ACL), Posterior Cruciate Ligament (PCL), Medial Collateral Ligament (MCL), and Lateral Collateral Ligament (LCL). The ACL, the ligament located in the center of the...
