目的 :观察人眼外肌栅栏氏本体感受终端光镜结构。方法 :标本取自眼球摘除者和共同性斜视患者的眼外肌 ,Holm e′s银染法光镜观察。结果 :位于眼外肌肌腱连接处的感受器神经纤维终止于邻近单个梭外肌纤维的起始处或肌纤维的上、下两侧。结论 :感受器神经终端与单个梭外肌纤维紧密接触 ,为“流入学说”提供了形态学依据 OBJECTIVE: To observe the light microscopic structure of the main body of Fetal eye in human eye muscle. Methods: Specimens were taken from the extraocular muscles of patients with enocular remnant and common strabismus, and observed with Holm e’s silver staining. Results: The sensory nerve fibers located at the tendon junction of the extraocular muscles terminate at the beginning of adjacent single extrafusal muscle fibers or at the upper and lower sides of the myofibers. CONCLUSIONS: The terminals of sensory nerves are in close contact with single extrasolar muscle fibers, providing a morphological basis for the “influx theory”
