The neural histology of the human shoulder ligaments, glenoid labrum, and subacromial bursae were studied using a modified gold chloride stain. Two morphological types of mechanoreceptors and free nerve endings were found in the ligaments. Slow adapting Ruffini end organs and rapidly adapting Pacinian corpuscles were identified in the superior, middle, inferior, and the posterior glenohumeral ligaments. These specialized proprioceptive nerve endings were also found in the coracoclavicular, and coracoacromial ligaments. Only free nerve endings were found in the glenoid labrum and these were located in the peripheral half. Scattered free nerve endings were found throughout the subacromial bursae. This is the first histological evidence of neural receptors in the human shoulder ligaments, glenoid labrum, and the subacromial bursae. Any disruption of the labrum or these ligaments by trauma or surgery can deprive the shoulder of mechanical stability, and may cause a decrease in proprioception because of the loss of these afferent neural receptors. Removal of symptomatic, inflamed bursae may decrease pain signals from this area of the shoulder.
采用改良的氯化金染色法对人类肩部韧带、盂唇和肩峰下滑囊的神经组织学进行了研究。在韧带中发现了两种形态类型的机械感受器和游离神经末梢。在肩肱上、中、下及后韧带中识别出了慢适应鲁菲尼终末器官和快适应帕西尼小体。在喙锁韧带和喙肩韧带中也发现了这些特殊的本体感觉神经末梢。在盂唇中仅发现了游离神经末梢，且位于周边半部。在整个肩峰下滑囊中发现了散在的游离神经末梢。这是人类肩部韧带、盂唇和肩峰下滑囊中神经感受器的首个组织学证据。因创伤或手术导致的盂唇或这些韧带的任何破坏都可能使肩部失去机械稳定性，并可能因这些传入神经感受器的丧失而导致本体感觉下降。切除有症状的炎性滑囊可能会减少来自肩部该区域的疼痛信号。
