Question

Quizplus · Accepted Answer

Intrafusal muscle fibers are found within muscle spindles, which are sensory organs within muscles that detect changes in muscle length and provide feedback to the central nervous system about muscle contractions. They are not directly responsible for muscle contractions, and they are not located at the junction between a muscle and tendon.
