cricothyroid

The distance from the root of PN to the level of the subclavian vein and to cricothyroid joint were ( 7.2 ± 1.6) cm and ( 5.5 ± 1.4) cm, respectively. The former was at least 1.5 cm longer than the latter.

膈神经起点至锁骨下静脉上缘平面及至环甲关节的距离平均（x±s）分别为（72±16）cm及（55±14）cm，两者相差至少15cm。

An experimental study on the originating nuclei of the nerve to cricothyroid muscle and their properties in the rabbit

家兔环甲肌运动神经的起核及其性质的实验研究

Conclusion The recurrent laryngeal nerve innervate all the intrinsic muscles of the larynx except cricothyroid muscle, paralysis of the nerve leads to atrophy of related muscles.

结论喉返神经支配除环甲肌以外的所有喉内肌，其麻痹后所支配的肌肉群可以发生去神经性萎缩。

Objective : To investigate the feasibility of cricothyroid laryngotomy instead of incision of trachea.

目的: 环甲膜切开选择性代替气管切开的可行性.

Results Amplitude and time limit of cricothyroid muscle, and time limit of muscles of tongue in the patient of true bulbar paralysis after treatment decreased as compared with that before treatment respectively.

结果：真性球麻痹患者疗后环甲肌振幅、时限及舌肌时限较疗前降低。

Mechanical analysis on the movement of cricothyroid joint and the tonicity of vocal cord

环甲关节运动与声带张弛的力学分析

The originating nuclei of nerve innervating cricothyroid muscle ( CTm) and its location in the brain stem were traced with CT-HRP and its property was observed using AChE histochemical and ENK immunohistochemical techniques.

本文用CT-HRP追踪了环甲肌运动神经的起核及其在脑干中的位置，并用AChE组织化学和ENK免疫组化技术观察了它们的性质。

Anatomic character and movement mode of cricothyroid joint

环甲关节解剖特征及其运动方式分析

Except the cricothyroid muscle, all the laryngeal intrinsic muscles are innervated by the anterior branch of the recurrent laryngeal nerve. In 88% of the cases, the posterior cricoarytenoid muscle is innervated by two nervous pedicle, the others are innervated by a single nervous pedicle.

喉内肌除环甲肌外，均由喉返神经前支支配，其中88%的环杓后肌为喉返神经前支发出单支支配；
