This ligament becomes part of the supraspinous ligament at C7. It limits hyperflexion of the neck. Supraspinous ligament This is a thick ligament connecting the spinous processes of C7 down to the L3 or L4 vertebrae. It joins other ligaments to limit flexion of the spinal column. This ligament is attached to the posterior surface of the vertebrae body and the intervertebral discs in the spinal canal. It starts from C2 and extends downward to the sacrum. It prevents hyperflexion. It also supports the spinal column. Located within the spinal canal, it is found on the posterior bodies of the vertebrae. It starts at C2 and moves downward to the sacrum. It prevents hyperflexion. It also supports…What are the origins and insertions of the external oblique muscles?
