title: Similarities in the surface area/volume ratio in the fibers of the recurrent laryngeal nerve can explain the symmetry in the vocal fold mobility?
abstract: We demonstrate in this paper that although there are statistical differences for all morphometric data [axon length, axon diameter, myelinated fiber diameter and degree of the myelination (g-Ratio)] between the fibers of recurrent laryngeal nerve right and left, the surface area/volume ratio in the fibers of both nerves is exactly the same (1/1.7). Thereby, this paper presents the hypothesis that this similarity between the nerves can actually trigger a considerable synchrony in mobility of the intrinsic muscles of the larynx that control of the vocal folds.
