喉是参与呼吸的上呼吸道器官,吞咽,语音制作,和气道保护。这些复杂的功能取决于声带(VF)运动,依次通过喉内肌(ILM)的作用促进。每个ILM收缩的必要精确和近乎瞬时的调制取决于喉的本体感受神经支配。功能失调的喉本体感觉可能导致疾病,如喉肌张力障碍,吞咽困难,声带麻痹,和瘫痪。虽然骨骼肌中的本体感受系统源自体节已得到很好的描述,控制诸如VF之类的头部和颈部结构的本体感受电路没有得到很好的表征。两个多世纪以来,研究人员调查了规范的本体感受器官,肌肉纺锤体,高尔基肌腱器官,存在于ILM中,具有可变的发现。目前的工作是对喉本体感觉的外周成分的最新审查,包括喉中规范和可能的替代本体感受电路元素的当前知识。
The larynx is an organ of the upper airway that participates in breathing, glutition, voice production, and airway protection. These complex functions depend on vocal fold (VF) movement, facilitated in turn by the action of the intrinsic laryngeal muscles (ILM). The necessary precise and near-instantaneous modulation of each ILM contraction relies on proprioceptive innervation of the larynx. Dysfunctional laryngeal proprioception likely contributes to disorders such as laryngeal dystonia, dysphagia, vocal fold paresis, and paralysis. While the proprioceptive system in skeletal muscle derived from somites is well described, the proprioceptive circuitry that governs head and neck structures such as VF has not been so well characterized. For over two centuries, researchers have investigated the question of whether canonical proprioceptive organs, muscle spindles, and Golgi tendon organs, exist in the ILM, with variable findings. The present work is a state-of-the-art
review of the peripheral component of laryngeal proprioception, including current knowledge of canonical and possible alternative proprioceptive circuitry elements in the larynx.
