The architectural features of the most peripheral parts of the microcirculatory bed were studied in selected skeletal muscles (cremaster, retractor, spinotrapezius, and ventral stripe of spinotrapezius) in rats and golden hamsters ranging in weight between 130 and 330 and 130 and 180 g, respectively. In the cremaster muscle of both species, a very complicated, irregular and heterogenous arrangement of terminal arterioles, as well as of postcapillary and collecting venules was found. In the retractor, the most regular arrangement was along the margins of the middle part of muscle, but an irregular brush-like branching of the terminal arterioles and collecting venules limits the use of these areas. Similarly, in spinotrapezius muscle the most regular vascular architecture, complicated by a different fashion of terminal arterioles and collecting venules, was along the ventral border of muscle. The most regular and simplest vascular arrangement was in the ventral stripe of spinotrapezius of the rat. Therefore, this muscle is recommended as most appropriate for intravital experimental studies of the skeletal muscle microcirculatory bed in all age and weight groups.
在体重分别介于130至330克和130至180克之间的大鼠和金黄地鼠中，对选定骨骼肌（提睾肌、缩肌、斜方肌和斜方肌腹侧条纹）微循环床最外周部分的结构特征进行了研究。在这两个物种的提睾肌中，发现终末小动脉以及毛细血管后微静脉和集合微静脉的排列非常复杂、不规则且不均匀。在缩肌中，最规则的排列沿着肌肉中部边缘，但终末小动脉和集合微静脉的不规则刷状分支限制了这些区域的使用。同样，在斜方肌中，最规则的血管结构沿肌肉腹侧边缘分布，不过终末小动脉和集合微静脉的分布方式不同，使其变得复杂。最规则且最简单的血管排列存在于大鼠斜方肌的腹侧条纹中。因此，推荐将这块肌肉用于所有年龄和体重组骨骼肌微循环床的活体实验研究。
