During movement, what happens to muscle spindles?

Explanation:
Muscle spindles act as stretch detectors inside a muscle, and the nervous system keeps them under tension during movement so they can reliably sense length changes. When a muscle lengthens, the spindle is stretched and sends more sensory signals, helping coordinate movement and protect against overextension. Even as the muscle contracts, mechanisms keep the spindle taut so it doesn’t lose sensitivity. Because of this, the spindle stays taut during movement, rather than becoming loose or slack. Atrophy is a longer-term change and isn’t a result of a single movement. So the best answer is that muscle spindles stay taut.
