What does a strain refer to?

A strain specifically refers to an injury involving the muscles or tendons, which are the tissues that connect muscles to bones. When a muscle or tendon is overstretched or torn, it results in a strain. This can occur due to sudden movements, excessive force, or repetitive use of the affected area. The focus is on the tissue's ability to withstand tension and the damage that can occur, such as tearing or stretching beyond its normal limits, leading to pain, swelling, and decreased function in the affected area.

The other options describe different types of injuries. A torn ligament pertains to sprains, while a broken bone refers to fractures. A dislocation involves the joint surfaces being displaced from their normal position. Understanding these distinctions is crucial for identifying the nature of an injury and applying the appropriate care or intervention.
