The sensory innervation of the anterior cruciate ligament (ligamentum cruciatum anterius) of the human knee joint was studied by light- and electron microscopy. The connective tissue between the synovial membrane and the cruciate ligament contains small Ruffini corpuscles and lamellar corpuscles with several inner cores. The connective tissue septa between the individual fascicles of the cruciate ligament contain Ruffini corpuscles and free nerve endings. The free nerve endings are innervated by C-fibres and myelinated A-delta fibres. The afferent axons of Ruffini corpuscles are myelinated and measure 4-6 microns in diameter, those of the lamellar corpuscles with several inner cores measure about 6 microns in diameter. It is discussed, whether these receptors of the anterior cruciate ligament may influence the muscle tone via polysynaptic reflexes.
通过光学显微镜和电子显微镜对人膝关节前交叉韧带的感觉神经支配进行了研究。滑膜与交叉韧带之间的结缔组织含有小的鲁菲尼小体和具有多个内核的板层小体。交叉韧带各束之间的结缔组织间隔含有鲁菲尼小体和游离神经末梢。游离神经末梢由C纤维和有髓A-δ纤维支配。鲁菲尼小体的传入轴突有髓，直径为4-6微米，具有多个内核的板层小体的传入轴突直径约为6微米。文中讨论了前交叉韧带的这些感受器是否可能通过多突触反射影响肌肉张力。
