a: Superficial view of the deep suboccipital region. The RCDmi and the RCDma are connected tightly. b: The connection between the RCDmi and the DAOM. The ventral surface of the RCDmi is connected by multiple dense fibrous tissues (arrow) to the DAOM (hollow star). c: The connection between the DAOM and the SDM. The DAOM was separated from its cranial attachment at the foramen magnum, and the ventral surface of the DAOM is connected by trabecular fibrous bundles (arrow) to the SDM (hollow triangle). Abbreviation: OCCI = occipital bone; RCDmi = rectus capitis dorsalis minor muscle; RCDma = rectus capitis dorsalis major muscle; DAOM = dorsal atlanto-occipital membrane; SDM = spinal dura mater; C1 = posterior arch of atlas.
