The posterior longitudinal ligament is situated within the vertebral canal.It extends across the posterior surfaces of the bodies of the vertebrae. [1] It extends superoinferiorly between the body of the axis superiorly, [1] and (sources differ) the sacrum and possibly the coccyx [1] or upper sacral canal [2] inferiorly.
Ossification of the posterior longitudinal ligament (OPLL) is a process of fibrosis, calcification, and ossification of the posterior longitudinal ligament of the spine, that may involve the spinal dura. [1]
The anterior longitudinal ligament and posterior longitudinal ligament are both illustrated in this image; the anterior longitudinal ligament is to the far left, while the posterior longitudinal ligament is left of the center. The longitudinal ligaments are two sets of ligaments that run along the spine. These are:
The tectorial membrane of atlanto-axial joint (occipitoaxial ligaments) is a tough membrane/ [1] broad, strong band [2] representing the superior-ward prolongation of the posterior longitudinal ligament (the two being continuous). [3] [1] [2] It attaches inferiorly onto (the posterior aspect of [2]) the body of axis. [3] It broadens superiorly.
A ligament is the fibrous connective tissue that connects bones to other bones. It also connects flight feathers to bones, in dinosaurs and birds. All 30,000 species of amniotes (land animals with internal bones) have ligaments. It is also known as articular ligament, articular larua, [1] fibrous ligament, or true ligament.

The bases of denticulate ligaments arise in the pia mater and are firmly attached to the arachnoid mater and dura mater at the apex. [2] The denticulate ligaments extend across the subarachnoid space between anterior nerve roots and posterior nerve roots, piercing the intervening spinal arachnoid mater to reach the dura.
The posterior sacroiliac ligament is situated in a deep depression between the sacrum and ilium behind; it is strong and forms the chief bond of union between the bones. It consists of numerous fasciculi , which pass between the bones in various directions.
