The suboccipital region is a complex anatomical structure with the rectus captis posterior major (RCPma), the rectus capitis posterior minor (RCPmi), and the obliquus capitis inferior (OCI) as part of an important anatomical structure in this region for connecting with the dura mater via the myodural bridge (MDB) (Hack et al, 1995; Pontell et al, 2013; Scali et al, 2013; Su et ail, 2013; Zheng et al.
