从动物的进化史知道喉的功能主要是保护功能,喉的肌肉像括约肌,吞咽时关闭声门,防止误吸.喉反射的传入神经是喉上神经内支,反射中枢位于延脑,传出神经是迷走神经的分支,即喉返神经和喉上神经的外支.通过电检查这个反射,可辅助诊断喉的周围神经病变和中枢病变.1976年Sasaki C.T.等报道动物实验及三名喉癌病人的喉反射检查结果.
From the evolutionary history of animals know that the main function of the larynx is to protect the function of the throat muscles like the sphincter, closing the glottis when swallowing, to prevent aspiration. The imported nerve of the laryngeal nerve is the branch of the laryngeal nerve, reflex center located in the brain, The exit nerves are the branches of the vagus nerve, the recurrent nerve of the laryngeal nerve and the branch of the laryngeal nerve, which can assist in the diagnosis of peripheral neuropathies and central lesions in the larynx by examining the reflexes electronically. In 1976 Sasaki CT et al. The patient’s throat reflex examination results.
