Part I— “Jill” Questions

 

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

The difference between a tendon and a ligament is that a tendon attaches to muscle. (ie. muscle-bone, muscle-muscle, muscle- skin) A ligament, however, attaches to cartilage. (ie. cartilage-bone, cartilage-cartilage, bone-bone)

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 3 joints that form the ankle; they include the talocrural joint, the subtalar joint, and the Inferior tibiofibular joint. Jill most likely sprained her ankle. I feel this is the case because a strain is an injury of a muscle to tendon tissue, whereas a sprain is an incomplete/complete tear of the supporting ligaments of a joint. Because of this, Jill mostly experienced a sprain to her ankle.

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

The 4 ligaments of the knee are the ACL, LCL, MCL, and PCL. The Anterior cruciate ligament is located in the center of the knee. This ligament controls rotation and forward movement. Lateral collateral ligament is located on the outside side of the knee, giving stability to the outer knee. Medial collateral ligament is located on the inside of the knee, giving stability to the inner knee. Posterior cruciate ligament is located in the center of the knee, and controls backward movement of the tibia.

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
