title: Microcirculation of the extra-ocular muscles of rats. A scanning electron-microscopic corrosion cast study.
abstract: Specific researches, employing corrosion casts, were performed on different skeletal muscles, but not on extra-ocular muscles (EOMs). The microvascular bed of EOMs was studied by the corrosion cast technique in the rat. Two histologically and physiologically different layers were present in the EOMs. On the whole, the capillary pattern of EOMs was less dense than in the other skeletal muscles. The EOM orbital layer turned out to have a higher number of transverse anastomoses and tuning-fork divisions than the global layer had. These different microcirculatory patterns can be related with the physiological function and the anatomical situation of the EOMs.
