Fasciculi longitudinales inferior ligamenti cruciformis
Read moreStructure
Longitudinal bands are given off medially at the upper and lower borders of the transverse ligament of the atlas. The superior longitudinal band is strong and ascends between the apical ligament of the dense and the tectorial membrane. It attaches to the basilar part of the occipital bone. The inferior band is much weaker and passes inferiorly to the posterior surface of the axis.
