Which of the following best describes a sprain?

A sprain is best described as the stretching or tearing of ligaments, which are the tough connective tissues that connect bones to other bones at a joint. When a joint is subjected to excessive force or movement beyond its normal range, the ligaments can become overstretched or torn, leading to pain, swelling, bruising, and limited mobility in the affected area.

This definition encompasses the nature of a sprain, highlighting the involvement of ligaments specifically, which is critical for joint stability and function. Understanding that a sprain pertains to ligaments helps clarify its distinction from other injuries, such as strains, fractures, or dislocations, which involve muscles, bones, or a combination of both in different ways.
