What is the difference between a sprain and a strain?

The correct choice highlights a fundamental distinction in the anatomy and mechanisms of injury associated with sprains and strains. A sprain occurs when ligaments, the connective tissues that join bones at a joint, are stretched or torn. This type of injury usually results from a sudden twist, fall, or impact that forces the joint out of its normal position.

On the other hand, a strain involves muscles or tendons, which are the tissues that connect muscles to bones. A strain typically results from overstretching or over-tearing these structures, often due to excessive force or improper lifting techniques.

Understanding this difference is crucial, as each type of injury has its own treatment protocols and recovery times. While both can cause pain and limit mobility, the treatment strategies may vary based on whether the injury involves ligaments or muscles/tendons.
