The evolution of muscle spindles
Experimental Physiology, Volume 110, Issue 10, Page 1401-1421, October 1, 2025.Abstract Muscle spindles are stretch‐sensitive mechanoreceptors found in the skeletal muscles of most four‐limbed vertebrates. They are unique amongst sensory receptors in the ability to regulate their sensitivity by contraction of the intrafusal muscle fibres on which the sensory endings lie.
