Objective: This study aims to provide reference data about the density and distribution of muscle spindles (MS) in certain mimic muscles on human cadavers. Methods: Orbicularis oculi, orbicularis oris, zygomaticus major and buccinator muscles were obtained from 16 cadavers on both sides, and they were dissected into pieces according to muscle mass. Routine tissue processing procedures were applied to all samples. Dewaxed serial sections were stained with hematoxylin and eosin (H&E) and Masson's Trichrome staining to determine muscle spindles. They were examined and photographed under a light microscope. Results: The mean numbers of MS in the buccinator muscle were 2.22 (H&E), 2.37 (Masson's) on the right side and 2.42 (H&E), 2.16 (Masson's) on the left side. The following numbers (0.5 and 1.33) were detected on both sides for orbicularis oculi and orbicularis oris muscles, respectively. The mean numbers of MS were 2.1 (H&E), 1.85 (Masson's) on the right and 0.5 on the left for zygomaticus major. Light microscopic examination of 72 samples revealed that perimysium enclosing fascicles, skeletal muscle fibers, peripherally located nuclei, endomysium, blood vessels, and peripheral nerves were intact. External and internal connective tissue capsules and intrafusal muscle fibers were observed in the muscle spindles inside the perimysium and fascicles. Conclusion: The differences in density and distribution of muscle spindles were presented in certain mimic muscles. Therefore these differences may provide a basis to explain the mechanisms related to movement disorders of mimic muscles and functional indicators of pathological conditions. [ABSTRACT FROM AUTHOR] |
