The permanent and painful shortening of a muscle, tendon, or ligament is called a(n):

  1. Sprain

  2. Fracture

  3. Contracture

  4. Dislocation

The correct answer is: Sprain

A sprain is defined as the permanent and painful shortening of a muscle, tendon, or ligament. This is caused by an injury or strain, which can lead to inflammation and damage to the tissue. Options B, C, and D are incorrect because they refer to different types of injuries. A fracture is a break or crack in a bone, a contracture is the shortening and hardening of a muscle or other tissue, and a dislocation is when a bone is forced out of its normal position at a joint. These options do not match the definition of a sprain, so they are not the correct answer.
