在9具男性尸体上，对颈横突间后肌、肋短提肌和腰横突间外侧肌的神经分布进行了详细观察。这些肌肉中的任何一块都位于脊神经背侧和腹侧主支的起点之间。肋短提肌上段的神经供应绝大多数来自相应脊神经的两个主支，而下段的神经供应则来自各脊神经分叉处的中间支。肋短提肌的两种神经供应方式在中间节段相互转化。颈横突间后肌与胸区肋短提肌位置相似，均由脊神经的两个主支供应，故被认为是这些肌的上系列同源肌;腰横突间外侧肌也是如此，主要由脊神经的中间支供应，根据神经支配的位置和方式，提出颈横突间后肌，肋短提肌和腰横突间外侧肌应归入椎间外侧肌（焦v.l）作为从脊神经的两个初级支获得模糊特征的神经支配的连续同源肌肉，因此作为与背侧干肌或多或少不同的第三肌肉系统，（焦v. D，Nishi）和腹侧（焦v. V，Nishi），由脊神经的任一主支交替供应。
Distribution patterns of the nerves of supply to the intertransversarii posteriores cervicis, levatores costarum breves and intertransversarii laterales lumborum were carefully studied in nine body-halves of male human cadavers. Any of these muscles lie wegded in between the commencements of the dorsal and ventral primary rami of the spinal nerves. In the great majority of the cases the levatores costarum breves derived their nerve supply in the upper segments from both primary rami of the corresponding spinal nerves and in the lowest segments as therami intermediifrom the bifurcation of each spinal nerve into its primary rami. Both patterns of the nerve supply to the levatores costarum breves were turned into one another in the intervening segments. The intertransversarii posteriores cervicis of similar location to the levatores costarum breves in the thoracic region were regarded as the upper serial homologues of these muscles, because they were supplied by both primary rami of the spinal nerves, similarly the intertransversarii laterales lumborum, principally supplied by the rami intermedii of the spinal nerves, as the lower serial homologues of the same muscles.In view of location as well as mode of innervation it was proposed that the intertransversarii posteriores cervicis, levatores costarum breves and intertransversarii laterales lumborum should be grouped into themusculi intervertebrales laterales(abbrev.l) as the serially homologous muscles deriving innervation of an ambiguous character from both primary rami of the spinal nerves and therefore as the third muscle system more or less distinct from the musculi trunci dorsales (abbrev. D, Nishi) and ventrales (abbrev. V, Nishi) which are supplied alternatively by either of the primary rami of the spinal nerves.
