Intermitochondrial junctions with a spacing of 17-21 nm were observed in the superior rectus muscle of a rat. Periodic rounded densities are aligned midway between the apposed outer mitochondrial membranes at some of these junctions. Such densities have a diameter of about 8-10 nm and a center-to-center spacing of about 26-30 nm. These junctions occur in cases where one mitochondrial profile is enclosed within another or where two profiles are interlocked so that their combined overall form has a smoothly contoured profile. Intermitochondrial junctions seem not to have been previously described in muscle, but have been reported in other kinds of tissues. In agreement with those previous reports, the presently observed intermitochondrial junctions usually involve mitochondria that display atypical features indicative of tissue abnormality or stress. Such junctions were never observed in normal extraocular muscle.
在大鼠上直肌中观察到线粒体间连接，其间距为17 - 21纳米。在其中一些连接处，周期性的圆形致密物排列在相对的线粒体外膜之间的中间位置。这些致密物直径约为8 - 10纳米，中心间距约为26 - 30纳米。这些连接出现在一种线粒体轮廓被另一种包围的情况，或者两个轮廓相互连锁，以至于它们组合后的整体形态具有平滑轮廓的情况。线粒体间连接似乎此前在肌肉中未被描述过，但在其他类型的组织中已有报道。与之前的那些报道一致，目前观察到的线粒体间连接通常涉及显示出组织异常或应激非典型特征的线粒体。在正常眼外肌中从未观察到这种连接。
