Strains involve the tearing of which type of tissue?

Strains specifically refer to injuries involving the tearing of muscle fibers. When a muscle is overstretched or subjected to excessive force, the fibers can tear, resulting in a strain. This type of injury can vary in severity, ranging from mild strains with minimal tearing to more severe cases where a significant portion of muscle fibers is damaged.

While tendons can be associated with strains as they connect muscles to bones, the term "strain" directly refers to muscle injuries rather than tendon injuries. Injuries to tendons are typically classified as tendonitis or tendinopathy, and injuries to ligaments are classified as sprains, which are different from strains. Skin is also not classified under strains, as it is a separate type of tissue and does not experience tearing in the same context as muscles or tendons.
