本研究旨在从组织学层面检查头下斜肌（OCI）与颈硬膜之间的解剖关系。从方便获取的样本中选取了8具平均年龄为65±7.9岁的人体尸体进行枕下解剖。切取了12个OCI肌肉标本，其中100%都有肉眼可见的软组织束插入颈硬膜的后外侧。这12个肌 - 硬膜标本作为单一连续结构被切取，并送去进行苏木精 - 伊红（H&E）染色。一个样本还进行了免疫过氧化物酶染色。显微镜评估证实，在75%的标本中，有一个结缔组织桥从OCI肌主体发出并附着于颈硬膜的后外侧。其余25%的切片机切片无法在同一平面上获取肌肉、结缔组织和硬膜，因此无法进行正确分析。送去进行神经分析的样本对在OCI肌 - 硬膜桥内穿行的几个神经束呈阳性染色。本研究从组织学上证实了存在一个将OCI肌肉与硬膜相连的结缔组织桥，并且在这种连接中存在神经组织，这值得进一步研究。这种结构可能是正常人体解剖结构的一个组成部分。除了其在人体稳态中假设的作用外，它可能也与某些神经病理状况有关。（C）2013爱思唯尔股份公司。保留所有权利。
This study was designed to examine the anatomical relationship between the obliquus capitis inferior (OCI) muscle and the cervical dura mater at the histological level. Eight human cadavers, with an average age of 65 +/- 7.9 years were selected from a convenience sample for suboccipital dissection. Twelve OCI muscle specimens were excised, 100% of which emitted grossly visible soft tissue tracts that inserted into the posterolateral aspect of the cervical dura. These 12 myodural specimens were excised as single, continuous structures and sent for H&E staining. One sample also underwent immuno-peroxidase staining. Microscopic evaluation confirmed a connective tissue bridge emanating from the OCI muscular body and attaching to the posterolateral aspect of the cervical dura mater in 75% of the specimens. Microtome slices of the remaining 25% were not able to capture muscle, connective tissue and dura within the same plane and were therefore unable to be properly analyzed. The sample sent for neuro-analysis stained positively for several neuronal fascicles traveling within, and passing through the OCI myodural bridge. This study histologically confirms the presence of a connective tissue bridge that links the OCI muscle to the dura mater and the presence of neuronal tissue within this connection warrants further examination. This structure may represent a component of normal human anatomy. In addition to its hypothetical role in human homeostasis, it may contribute to certain neuropathological conditions, as well.
