开展研究的原因：需要研究更准确和完整地定义马环杓肌背侧的神经解剖学，这是开发用于喉返神经病变的神经假体的先决条件。目的：介绍马环杓肌背侧的解剖结构、神经支配、纤维类型和功能。方法：对无上呼吸道疾病史的马进行尸检，取喉31只，肉眼解剖25只。随后，对一部分喉部进行以下准备：组织化学染色（n = 5），运动终板进行Sihier和乙酰胆碱酯酶染色（n = 2）。另外收集了6个喉部，用于肌肉刺激研究。结果：在所有喉部均发现两个神经肌肉室（NMC），每个神经室由喉返神经的一个初级神经分支支配。刺激外侧NMC比内侧NMC产生更多的杓状软骨外侧移位(P
Reason for performing study: Studies are required to define more accurately and completely the neuroanatomy of the equine dorsal cricoarytenoid muscle as a prerequisite for developing a neuroprosthesis for recurrent laryngeal neuropathy.Objective: To describe the anatomy, innervation, fibre types and function of the equine dorsal cricoarytenoid muscle.Methods: Thirty-one larynges were collected at necropsy from horses with no history of upper airway disease and 25 subjected to gross dissection. Thereafter, the following preparations were made on a subset of larynges: histochemical staining (n = 5), Sihier's and acetylcholinesterase staining for motor endplates (n = 2). An additional 6 larynges were collected and used for a muscle stimulation study.Results: Two neuromuscular compartments (NMC), each innervated by a primary nerve branch of the recurrent laryngeal nerve, were identified in all larynges. Stimulation of the lateral NMC produced more lateral displacement of the arytenoid cartilage than the medial NMC (P
