The distribution and ultrastructure of sensory nerve endings were investigated in the deep lateral elbow region of the rat. Three zones of distribution of mechanoreceptors were distinguished, each in relation to the functional architecture of the connective and muscular tissue in that area: (1) a zone with muscle spindles, Golgi tendon organs, free nerve endings and single small lamellated corpuscles ('muscle-tendon spectrum'), situated in the middle third of the supinator muscle and its superficial aponeurosis; (2) a zone with small lamellated corpuscles and free nerve endings, situated pericapsularly to the humeroradial joint capsule ('shearing spectrum'): this moderately dense, irregular connective tissue is covered by the proximal continuation of the supinator's aponeurosis, and muscle fibers insert from beneath this aponeurosis, which displays, as a part of the joint capsule, a strong collagenous tissue plate; (3) a zone with only free nerve endings within the tendon-like, most proximal part of the supinator's aponeurosis, inserting into the periosteal layer of the lateral humeral epicondyle ('endotenonial spectrum'): it is part of the joint capsule. The ultrastructure of these sensory endings is described and the distribution pattern of the mechanoreceptors observed is discussed in relation to the classification into 'muscle receptors' and 'joint receptors'.
对大鼠肘部外侧深部区域的感觉神经末梢分布及超微结构进行了研究。区分出了机械感受器的三个分布区域，每个区域都与该区域结缔组织和肌肉组织的功能结构相关：(1) 一个包含肌梭、高尔基腱器官、游离神经末梢和单个小的板层小体的区域（“肌腱 - 肌肉频谱”），位于旋后肌及其浅腱膜的中三分之一处；(2) 一个包含小的板层小体和游离神经末梢的区域，位于肱桡关节囊周围（“剪切频谱”）：这种中等密度的不规则结缔组织被旋后肌腱膜的近端延续部分覆盖，肌肉纤维从该腱膜下方插入，该腱膜作为关节囊的一部分，有一个强大的胶原组织板；(3) 一个仅在旋后肌腱膜最近端的腱样部分内有游离神经末梢的区域，该部分插入肱骨外侧髁的骨膜层（“腱内膜频谱”）：它是关节囊的一部分。描述了这些感觉末梢的超微结构，并根据“肌肉感受器”和“关节感受器”的分类对观察到的机械感受器分布模式进行了讨论。
