Spiral Nerve-endings (Proprioceptors) in the Human Vocal Muscle


THE problem of the proprioceptive innervation of the human vocal muscle is still controversial1. The presence of a proprioceptive mechanism controlling the fine adjustments of the vocal cords has been postulated by some authors; it has been rejected on theoretical grounds by others. Paulsen2 assumes that the tension of the vocal muscle would have central control alone. A peripheral proprioceptive mechanism would be rather a hindrance for normal phonation. The same was said to be true of the extrinsic eye muscles, in which nevertheless proprioceptors have been demonstrated within the past ten years histologically as well as by electrical records3–5.
