The ultrastructure and location of sensory nerve endings in the shoulder-joint capsule, its tendinous reinforcements and in the periarticular connective and muscle tissue have been studied by means of light and electron microscopy in adult female white NMRI-F2 laboratory mice, aged 2.5-13 months. Most of the sensory nerve endings were detected in the fibrous layer of the joint capsule or in the inserting tendons. The identified lamellated corpuscles of the Pacini type are small and sometimes associated with Golgi tendon-organs. Large Vater-Pacini corpuscles were not detected. Ruffini corpuscles are found in small numbers only in the moderately dense connective tissue of the joint capsule. Golgi tendon organs were found mainly at the muscle-tendon junction of the muscles surrounding the joint. Muscle spindles have been identified mainly in periarticular muscles close to the muscle-tendon junctions. The number and distribution of the different types of mechanoreceptors investigated in the present study suggest that periarticular corpuscular sensory nerve endings play an important role in shoulder-joint control and mobility. The occurrence of small uniformly shaped lamellated corpuscles of the Pacini type in qualitatively different areas of surrounding tissue implies that they are susceptible to different kinds of mechanical stimuli.
利用光学显微镜和电子显微镜，对2.5至13月龄成年雌性白色NMRI-F2实验室小鼠肩关节囊、其腱性增强结构以及关节周围结缔组织和肌肉组织中感觉神经末梢的超微结构和位置进行了研究。大多数感觉神经末梢在关节囊的纤维层或插入肌腱中被检测到。所识别出的帕西尼型板层小体较小，有时与高尔基腱器官相关。未检测到大型瓦尔特 - 帕西尼小体。鲁菲尼小体仅少量存在于关节囊的中等致密结缔组织中。高尔基腱器官主要在围绕关节的肌肉的肌腱连接处被发现。肌梭主要在靠近肌腱连接处的关节周围肌肉中被识别出。本研究中所研究的不同类型机械感受器的数量和分布表明，关节周围小体感觉神经末梢在肩关节控制和活动中起重要作用。在周围组织性质不同的区域出现形状均匀的帕西尼型小板层小体，这意味着它们易受不同种类的机械刺激。
