This article summarizes the authors' previous studies on proprioceptors in extraocular muscles (EOMs) of mammals and man. They report on muscle spindles in the EOMs of man, Golgi tendon organs in the EOMs of even-toed ungulates, and palisade endings in the EOMs of the cat. Muscle spindles: Muscle spindles are present in the EOMs of some mammals and in the EOMs of man. Compared with muscle spindles in other skeletal muscles, those in human EOMs exhibit structural differences. These structural differences may indicate a special function. Golgi tendon organs: Golgi tendon organs are absent in human EOMs. Golgi tendon organs exhibiting a specific morphology are present in the EOMs of even-toed ungulates. Their high number and rich innervation indicate functional importance. Palisade endings: Palisade endings are nervous end organs confined to the EOMs of mammals and man. It is assumed that these organs have a proprioceptive function. The authors show that palisade endings are immunoreactive for antibodies against choline acetyltransferase. Neuromuscular contacts, if present in palisade endings, are alpha -bungarotoxin positive as well. Taken together, these results show that palisade endings exhibit molecular characteristics of effector organs.
本文总结了作者之前关于哺乳动物和人类眼外肌（EOM）中本体感受器的研究。他们报告了人类EOM中的肌梭、偶蹄目动物EOM中的高尔基腱器官以及猫EOM中的栅栏状末梢。肌梭：肌梭存在于一些哺乳动物和人类的EOM中。与其他骨骼肌中的肌梭相比，人类EOM中的肌梭表现出结构差异。这些结构差异可能表明其具有特殊功能。高尔基腱器官：人类EOM中不存在高尔基腱器官。具有特定形态的高尔基腱器官存在于偶蹄目动物的EOM中。它们数量众多且神经支配丰富，表明其功能重要。栅栏状末梢：栅栏状末梢是局限于哺乳动物和人类EOM的神经终末器官。据推测，这些器官具有本体感受功能。作者表明，栅栏状末梢对胆碱乙酰转移酶抗体具有免疫反应性。如果栅栏状末梢存在神经肌肉接触，它们对α-银环蛇毒素也呈阳性反应。综上所述，这些结果表明栅栏状末梢具有效应器官的分子特征。
