What is a muscle strain?

• A. Stretching or tearing of a muscle or tendon
• B. Break in a bone
• C. Dislocation of a joint
• D. Tear of a ligament

Answer: (A)

A muscle strain is an injury to muscle tissue or its tendon caused by overstretching or excessive contraction, which means the muscle fibers are stretched or torn. This directly matches the description of stretching or tearing of a muscle or tendon. It’s different from a break in a bone (fracture), a joint moving out of place (dislocation), or a tear of a ligament (sprain). Common examples include pulled hamstrings or calf strains, and symptoms typically include localized pain, weakness, swelling, and sometimes bruising. Recovery emphasizes protecting the area, rest, gradual rehabilitation, and strengthening to prevent recurrence.
