Answers:

1. True. The longest and strongest bone in our body is the femur, aka the thigh bone.

2. False. The hip is usually described as the joint that connects the femur (thigh bone) to the pelvis.

3. False. Our rotator cuff is made up of 4 muscles, including the supraspinatus, infraspinatus, subscapularis, and teres minor. These 4 muscles are extremely important for our shoulder stability.

4. False. Our biceps is a muscle that has 2 heads, including the long head, and the short head. The biceps is located in our upper arms and is mainly responsible for flexing our elbows.

5. False. The Achilles tendon is located at the back of our heel, attaching the calf muscles (triceps surae: gastrocnemius and soleus) to the heel (calcaneus). The thick band of connective tissue that is located on the outer side of the thigh is called the iliotibial band, aka IT band.

6. Ture. There are 3 muscles in our hamstrings, including the biceps femoris, semitendinosus, and semimembranosus.

7. False. The smallest bone in our body is in our ears, which is called the stapes.

8. False. Our skeleton matures when we are around 25 years old.

9. True. ACL, or anterior cruciate ligament, is a ligament in your knee that is responsible for stabilizing your knees.

10. False. There are 12 ribs in our body but not all of them attach to the sternum. The first 7 of them (ribs 1-7) are true ribs that attach directly to the sternum. The next 3 of them (ribs 8-10) are false ribs that attach to the 7th costal cartilage above and the last 2 of them (ribs 11-12) are floating ribs that do not attach to the sternum and only attach to the spine.
