arytenoid

The External Laryngeal Nerve is a motor nerve, innervating the cricothyroid muscle and part of the transverse arytenoid muscle.

喉上神经外侧支为运动神经，支配环甲肌和部杓横肌。

The anterior two third of glottis (phonatory portion), mucosa over the posterior commissure and the arytenoids muscle all remain intact.

此过程只影响杓软内侧，然而声门前三的发声区，后黏合处的黏膜及杓肌皆保持完好。
