用组织化学方法对7例喉切除手术切除的人喉肌肉进行了肌动肌球蛋白ATPase检测。不同的肌肉含有ATPase低纤维(I型)和ATPase高纤维(II型)的混合物。其中，甲状旁肌的II型纤维比例最高(65%)，环踝后肌的I型纤维比例最高(67%)。其他喉部肌肉有中间瓣膜。到目前为止，所有人类喉部肌肉中I型纤维的比例都高于动物的相应肌肉，这一发现可能与语言的发展有关。
The muscles from seven human larynxes removed by laryngectomy have been examined for actomyosin ATPase by histochemical methods. The various muscles contained a mixture of ATPase low (type I) and ATPase high (type II) muscle fibres. The thyreoarytenoid muscle had the highest proportion of type II fibres (65%) and the posterior cricoarytenoid muscle had the highest proportion of type I fibres (67%). The other laryngeal muscles had intermediate valves. All human laryngeal muscles had a higher percetage of type I fibres than the corresponding muscles in animals so far examined, a finding which may be related to the development of speech.
