Lesson 2.3: Physical Activity and Injury
Question
Injuries from physical activity occur most often to skin, bones, ligaments, and tendons. What is the difference between ligaments and tendons?

Lesson 2.3: Physical Activity and Injury
Answer
• Ligaments are tissues that connect bones together.
• For example, knee ligaments connect the bones of the upper and lower leg (femur to the tibia and fibula) (see picture).

Lesson 2.3: Physical Activity and Injury
Answer (continued)
• Tendons are tissues that connect muscles to bone.
• For example one tendon connects the muscle of the upper leg to the kneecap (see previous picture).
