- In human sensory reception: Nerve function
The receptors and the gamma fibres of the muscle spindle form a neuromuscular loop that ensures that tension on the spindle is maintained within its efficient operating limits. The excitability of the muscle spindle also can be influenced through other neural pathways that control the general level of excitability…

- In human nervous system: Muscle spindles
…the muscle spindle receive specialized fusimotor nerve fibers. These are much smaller than the motor axons innervating extrafusal muscle fibers and are given the name gamma (γ) efferents. Because their only function is to regulate the behavior of the muscle spindles, their stimulation produces no significant contraction of the muscle…
