In a strain, which tissues are injured?

In a strain, which tissues are injured?

• A. Bones and muscles
• B. Fascia and joint capsules
• C. Ligaments and joint capsules
• D. Muscles and tendons

Answer: (D)

A strain targets the musculotendinous unit—the muscle fibers and the tendon that attaches the muscle to bone. Overstretching or tearing within this unit is what defines a strain, so muscles and tendons are the structures injured. That’s why this option fits best: it reflects the primary tissues involved when a muscle is strained, such as a hamstring strain where both the muscle fibers and the tendon at the musculotendinous junction are affected. The other tissues point to different injuries. Bones and muscles would suggest a fracture with muscle involvement for the second part, not a primary strain. Fascia and joint capsules aren’t the typical primary structures torn in a strain; injuries there are less about strain and more about fascial or capsular issues. Ligaments and joint capsules are classically involved in sprains, not strains.
