| Abstract: | Objective:In order to investigate the structure of palisade endings (PEs) which are proprioceptors in human extraocular muscles under light microscopy.Methods:The samples were obtained from the extraocular muscles of patients who were enucleated and those who were suffering from concomitant strabismus.Results:The nerve fibers of PEs locating at the myotendinous junction of extraocular muscles terminated on the tip or the sides of a nearby single extrafusal fiber.Conclusion:The studies indicated that PEs are connected closely with the extrafusal fibers,providing a morphological evidence for the Inflow Theory |

| Keywords: | palisade endings proprioceptor structure under light microscopy extrafusal fiber inflow theory |
